The TAJA226K010RNJ is a 22 µF tantalum capacitor rated at 10 V, ±10% tolerance, in the TAJ series from KYOCERA AVX. The 3 Ohm ESR sets the ripple voltage and self-heating.
1206 case — rework-friendly footprint, standard reflow profile
The 1206 (3216 Metric) case is a common size that reflows well with a standard lead-free profile. The molded body has clear polarity marking — the stripe on the top indicates the positive terminal — so orientation is easy to verify under a microscope after reflow. The seated height is 1.80 mm max, which fits under most low-profile enclosures.
Active production — no end-of-life risk on this BOM line
It is a current production part from KYOCERA AVX, orderable through independent distribution. The wide temperature span also means the capacitance drift over temperature is within the ±10 % tolerance band across most of the range.
