| Description |
The C3216X7T2J473KT000N is a high-voltage, surface-mount 47nF (0.047µF) multilayer ceramic chip capacitor (MLCC) manufactured by TDK Corporation. Designed for electronic circuits requiring compact dimensions, high DC voltage capability, and reliable capacitive performance, the component combines a 630V DC voltage rating, X7T temperature characteristic, ±10% nominal capacitance tolerance, and a standard 1206 SMD package. The C3216X7T2J473KT000N belongs to the TDK C3216 commercial-grade mid-voltage ceramic capacitor series. This series is designed to provide high capacitance values and elevated voltage ratings in compact surface-mount packages, making it suitable for power supply filtering, voltage converter circuits, industrial electronic equipment, and general-purpose high-voltage applications. The device provides a nominal capacitance of 47nF (0.047µF or 47000pF) with a capacitance tolerance of ±10%. This tolerance specifies the allowable initial capacitance variation under the manufacturer's reference measurement conditions. Actual capacitance during operation also depends on temperature, applied DC bias voltage, operating frequency, and dielectric aging. A major characteristic of the C3216X7T2J473KT000N is its high 630V DC rated voltage. This voltage rating allows the capacitor to be considered for electronic circuits operating at substantially higher DC voltages than conventional low-voltage ceramic capacitors. The maximum operating voltage must remain within the manufacturer's specifications, including any applicable derating requirements. The capacitor uses an X7T Class II ceramic dielectric, which provides a useful combination of capacitance density, operating temperature capability, and compact component dimensions. Class II ceramic materials offer relatively high capacitance values in small packages but exhibit capacitance variation with temperature, applied voltage, and operating time. The X7T temperature characteristic specifies a capacitance change of approximately +22% to -33% over the operating temperature range of -55°C to +125°C, relative to the specified reference temperature conditions. This characteristic makes the device suitable for applications that can accommodate the dielectric's temperature-dependent capacitance variation. Unlike C0G or NP0 ceramic capacitors, which provide extremely stable capacitance characteristics, the X7T dielectric is optimized for achieving higher capacitance values within a compact package. Designers should consider the dielectric's capacitance variation when selecting the component for filtering, coupling, and energy-storage applications. The C3216X7T2J473KT000N is specified for an operating temperature range of -55°C to +125°C. This extended temperature capability supports use in industrial electronics, power conversion systems, embedded control equipment, and electronic assemblies exposed to substantial ambient temperature variations. The capacitor provides a maximum specified dissipation factor of 2.5% under the manufacturer's applicable test conditions. Dissipation factor represents dielectric losses and is an important parameter when evaluating capacitor efficiency, AC signal behavior, and internal heating in electronic circuits. The device also features a minimum specified insulation resistance of 10000MΩ under the applicable measurement conditions. High insulation resistance helps minimize DC leakage current through the dielectric and supports reliable operation in voltage filtering, coupling, and general-purpose electronic circuits. As a multilayer ceramic capacitor, the C3216X7T2J473KT000N is constructed using multiple internal ceramic dielectric layers separated by conductive electrode layers. These internal electrodes are connected to the external terminals, creating a parallel arrangement of capacitive elements within a compact monolithic component. This multilayer construction provides a relatively high capacitance value while maintaining small physical dimensions. It also supports low equivalent series inductance compared with many larger leaded capacitor technologies, making MLCCs useful for filtering and decoupling applications where high-frequency performance is important. The C3216X7T2J473KT000N is a non-polarized capacitor, meaning it does not have designated positive and negative terminals. This characteristic simplifies PCB assembly and allows the component to be used in circuits where the voltage polarity across the capacitor may vary, provided that all electrical operating limits are respected. The capacitor is particularly useful in high-voltage power supply filtering circuits. When connected across an appropriate DC supply rail, the component can help reduce unwanted voltage fluctuations and high-frequency noise generated by switching devices, control circuits, and other electronic components. In switching power supply (SMPS) applications, the C3216X7T2J473KT000N can provide local high-frequency bypassing and filtering in circuits operating within its voltage, current, and thermal limits. Its compact surface-mount construction makes it suitable for dense power supply PCB layouts where available board space is limited. The device may also be used in DC-DC converter circuits for high-frequency filtering, coupling, and noise reduction. The capacitor's suitability for a particular converter topology depends on the applied DC voltage, ripple current, switching frequency, transient conditions, and effective capacitance under DC bias. In high-voltage converter applications, designers must consider the DC bias characteristics of Class II ceramic dielectrics. The effective capacitance of an X7T MLCC can decrease as the applied DC voltage increases. Consequently, the nominal 47nF capacitance should not automatically be assumed to remain available at the maximum rated voltage. The effective capacitance should be evaluated using the manufacturer's capacitance-versus-DC-bias characteristics when designing precision filters, resonant networks, or circuits requiring a guaranteed minimum capacitance under operating conditions. The C3216X7T2J473KT000N can also be used in high-voltage decoupling applications, where a ceramic capacitor is placed close to a circuit or switching component to provide a local path for high-frequency current. Proper placement and short PCB connections help minimize parasitic inductance and improve filtering effectiveness. In electromagnetic interference (EMI) reduction circuits, the capacitor may be used as part of an appropriately designed filtering network to attenuate unwanted conducted noise. The filtering performance depends on the capacitor's impedance characteristics, circuit topology, frequency range, and surrounding components. The capacitor may also be considered for DC blocking and AC signal coupling applications where its capacitance, dielectric behavior, voltage rating, and frequency response are appropriate. For precision signal paths, designers should account for the voltage-dependent and temperature-dependent characteristics of the X7T dielectric. In industrial electronic equipment, the C3216X7T2J473KT000N can support power distribution filtering, converter noise suppression, and general-purpose capacitive functions. Its high rated voltage and extended temperature range make it useful in systems requiring compact high-voltage passive components. The device can also be used in embedded electronic systems and control modules incorporating high-voltage interfaces, power conversion stages, or analog filtering networks. The small package footprint allows integration into compact circuit boards without requiring the mounting space associated with larger through-hole capacitors. The C3216X7T2J473KT000N is supplied in a standard 1206 surface-mount package, also identified by the metric size designation 3216. The nominal component dimensions are 3.20mm length, 1.60mm width, and 1.60mm thickness. The corresponding current TDK ordering version specifies dimensional tolerances of approximately ±0.20mm for length, width, and thickness. These dimensions make the component compatible with standard 1206 MLCC PCB assembly processes, subject to the manufacturer's recommended land pattern and soldering requirements. The compact 1206 package provides a practical balance between PCB area, capacitance value, and high-voltage capability. Its surface-mount construction supports automated placement and efficient assembly in commercial and industrial electronics manufacturing. The capacitor features two external metallized terminals that provide electrical connection to the internal electrode structure. Proper solder joint formation and PCB pad geometry are important for maintaining mechanical integrity and reliable electrical connections during operation. TDK provides recommended PCB land pattern dimensions for both reflow and flow soldering processes. For reflow soldering, the recommended pad dimensions include approximately 2.00 to 2.40mm pad spacing dimension PA, 1.00 to 1.20mm dimension PB, and 1.10 to 1.60mm dimension PC, as defined in the manufacturer's package drawing. The C3216X7T2J473KT000N is suitable for standard reflow soldering processes when the manufacturer's specified soldering profile is followed. The corresponding TDK product family also supports flow soldering under applicable process conditions. Because multilayer ceramic capacitors are mechanically rigid components, excessive PCB bending, thermal shock, or improper handling can cause cracks in the ceramic body. Such cracks may reduce insulation resistance or cause electrical failures, particularly in high-voltage applications. Designers should therefore follow TDK's recommendations regarding PCB mechanical stress, component placement, soldering temperature profiles, and handling procedures. Additional attention should be given to board separation, connector insertion forces, and mounting locations near areas exposed to mechanical bending. The C3216X7T2J473KT000N belongs to the manufacturer's commercial-grade MLCC product range. It should not be assumed to carry automotive AEC-Q200 qualification. Applications requiring automotive-grade qualification should use an appropriately specified automotive capacitor series and verify the relevant manufacturer documentation. The component's 630V DC rating does not establish certification for direct connection across AC mains lines. Applications requiring X-class or Y-class safety capacitors must use components with the appropriate safety approvals and certifications for the intended application. The original C3216X7T2J473KT000N part number is associated with TDK's C3216X7T2J473K160AC ordering designation. The newer ordering number identifies the corresponding 47nF, ±10%, 630V, X7T, 1206 multilayer ceramic capacitor configuration. Designers should verify the manufacturer's part-number cross-reference when maintaining existing bills of materials or qualifying replacement components. The current TDK C3216X7T2J473K160AC ordering version is listed as a production-status component. It provides a manufacturer-supported option for designs requiring the same nominal capacitance, voltage rating, dielectric classification, and package dimensions. The capacitor is listed by TDK as RoHS compliant, REACH compliant, lead-free, and halogen-free under the manufacturer's applicable environmental compliance declarations. These characteristics support its use in modern electronics manufacturing processes requiring compliance with relevant environmental material restrictions. The device is supplied in embossed plastic tape-and-reel packaging, supporting automated component feeding and placement during surface-mount assembly. The standard manufacturer package quantity for the corresponding current ordering version is 2000 capacitors per reel. The reel packaging uses a nominal 180mm reel diameter and is suitable for high-volume automated SMT production. Tape-and-reel packaging helps protect the components during handling and supports consistent component orientation in automated assembly equipment. The combination of 47nF nominal capacitance, ±10% initial tolerance, 630V DC voltage rating, X7T dielectric with +22%/-33% temperature characteristics, -55°C to +125°C operation, 2.5% maximum dissipation factor, high insulation resistance, compact 3.20 × 1.60 × 1.60mm dimensions, and standard 1206 surface-mount packaging makes the C3216X7T2J473KT000N a practical choice for commercial high-voltage ceramic capacitor applications. The C3216X7T2J473KT000N is suitable for high-voltage power supply filtering, switching power supplies, DC-DC converters, DC bus noise filtering, high-voltage decoupling, electronic noise suppression, EMI filtering networks, industrial power electronics, voltage converter modules, analog and digital circuit filtering, DC blocking applications, signal coupling circuits, industrial control equipment, embedded electronic systems, high-voltage PCB assemblies, general-purpose electronic equipment, power management circuits, compact SMT electronic assemblies, and commercial high-voltage capacitor applications. |
