The TAJB157K002RNJ is a surface-mount molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 150 µF at 2.5 V with ±10% tolerance.
Housed in a 1411 (3528 Metric) case with size code B, dimensions 3.50 mm x 2.80 mm x 2.10 mm seated height. Surface-mount, supplied on tape and reel. The 1411 footprint is common — no fan-out surprises, but the 2.10 mm height may be tight under a low-profile shield or mezzanine card.
