Technical Details & Description

Molded tantalum for harsh environments

The TAJC475K020SNJ is a molded tantalum capacitor from the TAJ series, rated at 4.7 µF and 20 V with ±10% tolerance. The 1.4 Ohm ESR sets the ripple current ceiling and self-heating limit — for a 100 kHz switching regulator output, the ripple current should stay below the capacitor's rated ripple to keep the core temperature within the -55 to 125 °C operating range.

2312 case, size code C

The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm max. The manufacturer size code C corresponds to this footprint. Surface-mount assembly on a standard FR-4 board — the pad layout follows the 2312 recommended land pattern; no via-in-pad required.

Frequently asked questions

What is the closest pin-compatible alternative to TAJC475K020SNJ in the TAJ series?

Within the KYOCERA AVX TAJ series, any capacitor with the same 2312 case size (code C) and voltage rating is footprint-compatible. For a different capacitance value at 20 V, the TAJC series (e.g., TAJC106K020RNJ for 10 µF) shares the same case and pinout. Confirm the capacitance and ESR against your circuit requirements before substituting.
