The TPSC157K006R0200 is a 150 µF molded tantalum capacitor from the KYOCERA AVX TPS series, rated at 6.3 V with a 200 mOhm ESR. This combination suits it for bulk decoupling on low-voltage rails.
KYOCERA AVX lists the TPSC157K006R0200 as Active.
Housed in a 2312 (6032 Metric) surface-mount case, size code C, with dimensions 6.00 mm x 3.20 mm and a seated height of 2.80 mm. The 200 mOhm ESR keeps self-heating low during ripple current, but the PCB layout should still provide a thermal pad under the capacitor to dissipate heat into the board.
