Molded tantalum for harsh environments
The TAJS225M016RNJ is a molded tantalum capacitor from KYOCERA AVX's TAJ series, rated 2.2 µF at 16 V with ±20% tolerance. The 1206 (3216 metric) footprint is common enough that the board layout is usually a drop-in replacement for other 1206 tantalums in the same voltage class. The 6 ohm ESR is on the higher side for a 2.2 µF part — expect more self-heating than a low-ESR polymer would deliver, so keep the ripple current budget tight.
