The TAJC227K006RNJ is a molded tantalum capacitor from KYOCERA AVX's TAJ series, offering 220 µF capacitance with ±10% tolerance at a rated voltage of 6.3 V. With a 1.2 Ohm ESR, it provides moderate ripple current handling for bulk decoupling on 3.3 V or 5 V rails, where the 6.3 V rating gives headroom against startup overshoot. The C case size (2312 / 6032 Metric) fits a compact footprint on the board, surface-mount compatible with standard reflow profiles.
The molded construction and general-purpose feature set make it a drop-in choice for industrial and telecom power supplies that need a reliable tantalum across temperature extremes.
