T491A106K016AT / The <strong>T491A106K016AT</strong> is a general-purpose, surface-mount <strong>10µF 16V solid tantalum capacitor</strong> manufactured by <strong>KEMET, a member of the YAGEO Group</strong>. Designed for electronic circuits requiring compact dimensions, reliable capacitive performance, and stable DC power supply filtering, the device combines manganese dioxide (MnO2) solid electrolyte technology, ±10% capacitance tolerance, 3Ω maximum equivalent series resistance, and a standard 1206 (3216 Metric) A-case package.<br><br> The T491A106K016AT belongs to the <strong>KEMET T491 series of commercial-grade solid tantalum surface-mount capacitors</strong>. This product family is designed for general-purpose electronic applications requiring compact SMT construction, relatively high capacitance density, and compatibility with automated electronics manufacturing processes.<br><br> The device provides a nominal capacitance of <strong>10µF (10000nF or 10000000pF)</strong> with a specified capacitance tolerance of <strong>±10%</strong>. This tolerance corresponds to an initial capacitance range of approximately <strong>9µF to 11µF</strong> under the manufacturer's specified reference measurement conditions.<br><br> The T491A106K016AT features a rated DC working voltage of <strong>16V at temperatures up to +85°C</strong>. This voltage rating makes the capacitor suitable for various low-voltage electronic circuits, including power supply filtering, voltage regulator networks, local energy storage, and general-purpose DC decoupling applications.<br><br> For operation above +85°C, the maximum permissible working voltage must be reduced according to the manufacturer's temperature derating requirements. The corresponding rated voltage is approximately <strong>13.36V DC at +105°C</strong> and <strong>10.72V DC at +125°C</strong>.<br><br> The capacitor uses a <strong>solid manganese dioxide (MnO2) electrolyte</strong> with a tantalum pentoxide dielectric system. This construction provides a compact, polarized electrolytic capacitor with useful capacitance density and electrical characteristics for general-purpose electronic applications.<br><br> The internal structure consists of a porous tantalum anode, a thin tantalum pentoxide dielectric layer, and a solid manganese dioxide cathode system. These elements are incorporated into a molded surface-mount package designed to protect the internal capacitor structure during normal handling and PCB assembly.<br><br> Unlike conventional wet electrolytic capacitors, the T491A106K016AT does not contain a liquid electrolyte. Its solid electrolyte construction eliminates liquid electrolyte leakage and supports compact packaging suitable for high-density electronic circuit boards.<br><br> One of the important electrical characteristics of the T491A106K016AT is its <strong>maximum equivalent series resistance (ESR) of 3Ω at 100kHz and +25°C</strong>. ESR represents the resistive component of the capacitor's impedance and contributes to power dissipation when alternating or ripple currents flow through the device.<br><br> The 3Ω ESR rating must be considered when selecting the capacitor for power supply filtering, decoupling, and voltage regulator applications. Although suitable for many general-purpose circuits, the device is not intended to replace specialized ultra-low-ESR capacitors in applications requiring extremely high ripple current capability.<br><br> The T491A106K016AT provides a maximum specified <strong>DC leakage current of 1.6µA</strong>, measured after a five-minute voltage application at +25°C under the manufacturer's specified test conditions. Low leakage current is useful in circuits where excessive DC leakage could increase power consumption or influence sensitive bias voltages.<br><br> This leakage current characteristic makes the capacitor suitable for appropriately designed analog signal-conditioning circuits, DC voltage filtering networks, low-power electronic equipment, and general-purpose power management applications.<br><br> The device features a maximum specified <strong>dissipation factor of 6%</strong> at 120Hz and +25°C. Dissipation factor describes the electrical losses within the capacitor under alternating excitation and is an important consideration when evaluating filtering performance and capacitor heating.<br><br> The T491A106K016AT supports a specified <strong>RMS ripple current of 158mA at 100kHz and +25°C</strong>. Ripple current capability indicates the permissible alternating current flowing through the capacitor under the manufacturer's defined frequency and thermal conditions.<br><br> The allowable ripple current decreases as the operating temperature increases. The manufacturer specifies approximately <strong>142.2mA RMS at +85°C</strong> and <strong>63.2mA RMS at +125°C</strong> under the corresponding rated conditions.<br><br> These ripple current ratings are particularly important in switching power supply circuits, DC-DC converters, voltage regulator networks, and other electronic systems where periodic current variations flow through filtering capacitors. Designers should ensure that the expected ripple current remains within the applicable limits to prevent excessive internal heating.<br><br> The T491A106K016AT is specified for an operating temperature range of <strong>-55°C to +125°C</strong>. This extended temperature capability supports use in industrial electronic equipment, embedded control systems, telecommunications hardware, instrumentation, and general-purpose electronic assemblies exposed to changing environmental conditions.<br><br> The full 16V DC working voltage rating applies at operating temperatures up to +85°C. At higher temperatures, voltage derating is required, and designers should also account for temperature-dependent changes in leakage current, ESR, capacitance, and long-term reliability.<br><br> As a <strong>polarized solid tantalum capacitor</strong>, the T491A106K016AT must be installed with the correct electrical polarity. The positive terminal must be connected to the appropriate positive circuit potential relative to the negative terminal.<br><br> Solid tantalum capacitors are not intended for continuous reverse-voltage operation. Incorrect polarity, excessive applied voltage, or high surge currents may damage the capacitor and can result in overheating or catastrophic failure.<br><br> Appropriate <strong>voltage derating, current limiting, and transient protection</strong> should therefore be considered when designing circuits using the T491A106K016AT. These precautions are particularly important in low-impedance power supply applications where substantial inrush currents or voltage transients may occur.<br><br> For improved long-term reliability, the capacitor should be operated within the manufacturer's recommended voltage derating guidelines. The appropriate derating depends on the circuit impedance, supply voltage, operating temperature, surge current conditions, and intended application.<br><br> The T491A106K016AT is particularly useful in <strong>DC power supply filtering applications</strong>. When connected across a suitable DC supply rail, the capacitor can help reduce voltage fluctuations and provide localized energy storage for connected electronic components.<br><br> Its nominal <strong>10µF capacitance</strong> provides useful charge storage for low-voltage electronic circuits. The stored energy depends on the applied voltage and capacitance, allowing the device to help support short-duration current demands within the limitations of its ESR and ripple current ratings.<br><br> In <strong>voltage regulator circuits</strong>, the capacitor may be used as part of an input or output filtering network. The selected regulator's output capacitor requirements, including capacitance, ESR range, and stability conditions, must be checked before incorporating the T491A106K016AT into the design.<br><br> The capacitor can also provide <strong>power supply decoupling</strong> for analog and digital electronic systems. In these applications, it helps reduce supply voltage disturbances caused by changing circuit loads and provides a local reservoir of electrical charge.<br><br> For high-frequency decoupling applications, the T491A106K016AT may be combined with appropriately selected multilayer ceramic capacitors. Ceramic capacitors can provide lower impedance at higher frequencies, while the tantalum capacitor contributes bulk capacitance and damping characteristics to the overall power distribution network.<br><br> The T491A106K016AT may also be used in <strong>DC-DC converter circuits</strong> as part of suitable filtering or auxiliary decoupling networks. Designers must verify that the converter's ripple current, transient voltage, and stability requirements are compatible with the capacitor's specified electrical characteristics.<br><br> In <strong>analog circuit filtering applications</strong>, the capacitor can be used in appropriately designed low-pass filters, power rail conditioning networks, and signal stabilization circuits. Its polarity, leakage current, capacitance tolerance, and ESR should be considered when evaluating circuit performance.<br><br> The device is also suitable for <strong>industrial control equipment</strong>, where compact capacitors are required for local power supply filtering, electronic interface modules, and general-purpose control circuitry. Its extended operating temperature range supports use in industrial electronic assemblies exposed to varying ambient conditions.<br><br> In <strong>embedded electronic systems</strong>, the T491A106K016AT can support microcontroller-based control boards, communication modules, monitoring devices, and compact power management circuits. Its surface-mount construction allows integration into high-density printed circuit boards.<br><br> The capacitor can also be used in <strong>telecommunications equipment</strong> for power supply decoupling, auxiliary filtering, and local voltage stabilization. Its compact package dimensions make it suitable for communication hardware where available PCB area is limited.<br><br> In <strong>test and measurement instrumentation</strong>, the device may be used for local supply filtering, analog power conditioning, and auxiliary energy storage. Its specified leakage current, capacitance tolerance, and operating temperature range help designers determine suitability for measurement-related applications.<br><br> The T491A106K016AT is supplied in a compact <strong>1206 surface-mount package</strong>, also identified as <strong>3216 Metric or EIA A Case</strong>. The nominal package body dimensions are <strong>3.20mm length, 1.60mm width, and 1.60mm height</strong>.<br><br> The manufacturer's dimensional specification provides a length tolerance of <strong>±0.20mm</strong>, a width tolerance of <strong>±0.20mm</strong>, and a height tolerance of <strong>±0.20mm</strong>. The maximum specified package height is therefore approximately <strong>1.80mm</strong>.<br><br> The compact A-case package occupies approximately <strong>5.12mm²</strong> of nominal PCB body area, excluding any additional space required for solder pads and assembly clearances. This small footprint supports use in space-constrained electronic products and densely populated surface-mount circuit boards.<br><br> The capacitor features a <strong>molded resin body</strong> that provides mechanical protection for the internal tantalum capacitor structure. The package is designed for compatibility with standard automated surface-mount placement and reflow soldering processes.<br><br> The T491A106K016AT uses <strong>tin-finished surface-mount terminations</strong>, supporting compatibility with lead-free soldering processes. These external terminals provide electrical and mechanical connections between the capacitor and the printed circuit board.<br><br> Because the device is polarized, the package includes a polarity identification marking. During PCB assembly, the component orientation must be verified against the manufacturer's marking convention and recommended PCB footprint.<br><br> Proper <strong>PCB land pattern design, solder paste application, component orientation, and reflow temperature control</strong> are important for reliable assembly. Designers should follow the manufacturer's recommendations for mounting dimensions and soldering procedures.<br><br> The T491A106K016AT is listed as <strong>RoHS compliant</strong> and uses a lead-free tin termination finish. These characteristics support integration into electronic products manufactured under applicable restrictions on hazardous substances.<br><br> The capacitor has a manufacturer-specified <strong>Moisture Sensitivity Level of MSL 1</strong>. This classification indicates the lowest moisture sensitivity level under the applicable surface-mount component handling standard.<br><br> The manufacturer specifies a nominal <strong>shelf life of 156 weeks</strong> under the applicable storage conditions. Proper storage and handling procedures should be followed to maintain component condition and solderability before assembly.<br><br> The T491A106K016AT belongs to the <strong>commercial-grade KEMET T491 series</strong> and should not be assumed to carry AEC-Q200 automotive qualification. Applications requiring automotive-grade capacitors should use a specifically qualified product and verify the manufacturer's relevant qualification documentation.<br><br> The device is classified as a <strong>general-purpose molded tantalum capacitor</strong>. Its suitability for a particular application should be evaluated using the specified capacitance, rated voltage, temperature range, ESR, ripple current, leakage current, surge conditions, and expected service life.<br><br> The T491A106K016AT is supplied in <strong>tape-and-reel packaging</strong> for automated surface-mount assembly. The standard manufacturer package quantity is <strong>2000 capacitors per reel</strong>, making it suitable for automated pick-and-place equipment and high-volume electronics manufacturing.<br><br> The ordering designation <strong>T491A106K016AT</strong> identifies the KEMET T491 series, A-case package, 10µF nominal capacitance, ±10% tolerance, 16V rated voltage, and the applicable surface-mount ordering configuration.<br><br> The combination of <strong>10µF capacitance, ±10% tolerance, 16V DC rated voltage at +85°C, 10.72V DC operation at +125°C, 3Ω maximum ESR at 100kHz, 1.6µA maximum DC leakage current, 6% maximum dissipation factor, 158mA RMS ripple current at +25°C, -55°C to +125°C operating temperature range, and compact 1206 A-case packaging</strong> makes the T491A106K016AT a practical choice for general-purpose power supply filtering and electronic decoupling applications.<br><br> The <strong>T491A106K016AT</strong> is suitable for <strong>DC power supply filtering, voltage regulator input and output networks, power rail decoupling, local energy storage, DC-DC converter auxiliary filtering, analog power supply conditioning, industrial electronic equipment, embedded control systems, microcontroller power management, instrumentation circuits, telecommunications equipment, consumer electronics, electronic interface modules, low-current monitoring circuits, general-purpose signal filtering, compact SMT electronic assemblies, industrial automation, test and measurement equipment, and general-purpose solid tantalum capacitor applications</strong>.

T491A105K035AT / The <strong>T491A105K035AT</strong> is a general-purpose, surface-mount <strong>1µF 35V solid tantalum capacitor</strong> manufactured by <strong>KEMET, a member of the YAGEO Group</strong>. Designed for electronic circuits requiring stable capacitive performance, low DC leakage current, and compact physical dimensions, the device combines manganese dioxide (MnO2) solid electrolyte technology, ±10% capacitance tolerance, and a standard 1206 (3216 Metric) A-case package.<br><br> The T491A105K035AT belongs to the <strong>KEMET T491 series of commercial-grade solid tantalum surface-mount capacitors</strong>. This product family is designed for general-purpose electronic applications requiring reliable capacitance, compact SMT construction, and compatibility with automated electronics manufacturing processes.<br><br> The device provides a nominal capacitance of <strong>1µF (1000nF or 1000000pF)</strong> with a specified capacitance tolerance of <strong>±10%</strong>. The tolerance corresponds to an initial capacitance range of approximately 0.9µF to 1.1µF under the manufacturer's reference measurement conditions.<br><br> The T491A105K035AT features a rated DC working voltage of <strong>35V at temperatures up to +85°C</strong>. This rating makes it suitable for a variety of low-voltage and moderate-voltage electronic circuits, including power supply filtering, voltage regulator output networks, and general-purpose DC decoupling applications.<br><br> For operation above +85°C, the maximum permissible working voltage must be reduced according to the manufacturer's voltage derating requirements. At the maximum specified operating temperature of <strong>+125°C</strong>, the rated working voltage is reduced to <strong>23.45V DC</strong>.<br><br> The capacitor uses a <strong>solid manganese dioxide (MnO2) electrolyte</strong> with a tantalum-based dielectric system. Unlike wet electrolytic capacitors, solid tantalum capacitors do not rely on a liquid electrolyte, allowing the component to maintain a compact molded construction and providing useful electrical characteristics for general-purpose electronic applications.<br><br> The internal construction consists of a tantalum anode, a tantalum pentoxide dielectric layer, and a solid manganese dioxide cathode system. These materials form a polarized electrolytic capacitor with relatively high capacitance density compared with many alternative capacitor technologies of similar physical dimensions.<br><br> A significant characteristic of the T491A105K035AT is its specified <strong>equivalent series resistance (ESR) of 7Ω maximum at 100kHz and +25°C</strong>. ESR represents the resistive component of the capacitor's impedance and contributes to power dissipation when alternating or ripple currents flow through the component.<br><br> The ESR characteristic must be considered when selecting the capacitor for power supply filtering and decoupling circuits. Although the T491A105K035AT is suitable for many general-purpose filtering applications, its 7Ω ESR makes it less appropriate for high-ripple-current circuits requiring very low ESR capacitors.<br><br> The capacitor provides a maximum specified <strong>DC leakage current of 0.5µA</strong>, measured under the manufacturer's specified conditions after a five-minute voltage application at +25°C. Low leakage current is useful in circuits where excessive DC leakage could affect power consumption, bias voltages, or measurement accuracy.<br><br> This low leakage characteristic supports applications such as analog signal conditioning, reference voltage filtering, low-current power supply networks, and general-purpose electronic circuits requiring predictable DC capacitor behavior.<br><br> The T491A105K035AT features a maximum specified <strong>dissipation factor of 4%</strong>, measured at 120Hz and +25°C. Dissipation factor describes energy losses within the capacitor under alternating electrical excitation and is an important parameter when evaluating capacitor performance in filtering and power management applications.<br><br> The device supports a maximum specified <strong>RMS ripple current of 100mA at 100kHz and +25°C</strong>. Ripple current capability indicates the allowable alternating current through the capacitor under the applicable measurement and thermal conditions.<br><br> As the operating temperature increases, the permissible ripple current decreases. The manufacturer specifies approximately <strong>90mA RMS at +85°C</strong> and <strong>40mA RMS at +125°C</strong>, under the corresponding rated conditions.<br><br> These ripple current limits are important in switching power supply circuits, voltage regulators, and other electronic systems where alternating current components flow through the capacitor. Designers should ensure that the expected ripple current remains within the manufacturer's specified limits to avoid excessive internal heating.<br><br> The T491A105K035AT is specified for an operating temperature range of <strong>-55°C to +125°C</strong>. This wide temperature capability supports use in industrial electronic equipment, embedded control systems, instrumentation, and general-purpose electronic assemblies exposed to varying environmental conditions.<br><br> The capacitor's full 35V working voltage rating applies only within the specified temperature range up to +85°C. Operation at elevated temperatures requires appropriate voltage derating, and the designer should also consider the effects of temperature on leakage current, ESR, capacitance, and long-term reliability.<br><br> As a <strong>polarized solid tantalum capacitor</strong>, the T491A105K035AT must be installed with the correct electrical polarity. The positive terminal must be connected to the appropriate positive circuit potential relative to the negative terminal.<br><br> Unlike non-polarized multilayer ceramic capacitors, solid tantalum capacitors are not intended for continuous reverse-voltage operation. Incorrect polarity, excessive voltage, or high surge currents can damage the capacitor and may result in overheating or catastrophic failure.<br><br> The capacitor should therefore be used only within the manufacturer's recommended electrical operating conditions. Appropriate voltage derating, current limiting, and protection against voltage transients are particularly important in low-impedance power supply circuits.<br><br> For improved reliability, KEMET recommends applying suitable <strong>voltage derating practices</strong> according to the circuit's operating conditions and the applicable T491 series design guidelines. The required derating depends on factors such as circuit impedance, surge current exposure, temperature, and the intended application.<br><br> The T491A105K035AT is particularly useful in <strong>DC power supply filtering applications</strong>. When connected across a suitable power supply rail, the capacitor can help reduce voltage fluctuations and provide localized energy storage for connected electronic circuits.<br><br> In <strong>voltage regulator circuits</strong>, the capacitor may be used as part of an input or output filtering network.
