Molded tantalum, 0.68 µF at 35 V — what it does on the board
The TAJA684K035RNJ is a surface-mount molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 0.68 µF at 35 V with ±10% tolerance.
1206 footprint, molded case — board-fit and sourcing
Housed in a 1206 (3216 Metric) molded case, size code A, measuring 3.20 mm x 1.60 mm x 1.80 mm seated height — the footprint matches the standard 1206 tantalum land pattern; no pad geometry change needed if replacing a same-size part. General-purpose rating — no specific AEC-Q200 automotive qualification is listed, so confirm with the manufacturer if automotive-grade screening is required.
