The TAJS225M006RNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor rated 2.2 µF at 6.3 V with ±20% tolerance and an 18 Ohm ESR. The 1206 (3216 Metric) case is a standard surface-mount footprint, 3.20 mm x 1.60 mm, seated height 1.20 mm max.
The 18 Ohm ESR limits ripple current handling. For DC blocking or timing circuits where AC current is negligible, the ESR is not a concern.
Active production — no LTB urgency
The product status is Active. No last-time-buy window to chase; no forced redesign needed.
Footprint and board fit
The 1206 (3216 Metric) case has a manufacturer size code S. This is a two-terminal capacitor with standard solder pads — no via-in-pad or thermal pad required.
