The TAJC476K016RNJ from KYOCERA AVX is a TAJ Series general-purpose solid tantalum chip capacitor featuring resin-molded construction and J-lead surface-mount terminations. It provides 47µF capacitance, a 16VDC rated voltage, and ±10% capacitance tolerance, making it suitable for filtering, decoupling, energy storage, and low-power regulator circuits.
The device uses the C case size, corresponding to EIA 2312 / metric 6032-28. Nominal package dimensions are approximately 6.00mm × 3.20mm × 2.60mm, providing relatively high capacitance in a compact surface-mount footprint.
Its rated voltage is 16VDC at temperatures up to +85°C. At the maximum category temperature of +125°C, the specified category voltage is reduced to 10VDC, so appropriate voltage derating is required for high-temperature operation.
Maximum ESR is 0.5Ω at 100kHz, maximum dissipation factor is 6%, and maximum DC leakage current is 7.5µA for the 47µF/16V C-case configuration.
The specified 100kHz RMS ripple-current capability is 469mA at 25°C, 422mA at 85°C, and 188mA at 125°C. Actual circuit design should account for ambient temperature, operating frequency, thermal conditions, and recommended tantalum-capacitor voltage derating.
TAJ Series devices are polarized capacitors, with the package marking identifying the positive anode terminal. KYOCERA AVX specifies 100% surge-current testing for the TAJ family to support reliable general-purpose power applications.
The operating-temperature range is −55°C to +125°C. For a 16V-rated device, specified surge voltage is 20V up to +85°C and 13V at +125°C.
In the full ordering code, C identifies the case size, 476 represents 47µF, K specifies ±10% tolerance, 016 specifies 16VDC, R identifies pure-tin 7-inch reel packaging, and NJ is the standard specification suffix.
The 47µF/16V C-case configuration is specified as MSL 1. KYOCERA AVX identifies general low-power DC-DC and LDO circuits, entertainment/infotainment systems, and height-restricted designs among the primary TAJ Series applications.
