The TPSB157M002R0150: This is a current-production part you can order against a BOM line without worrying about a last-time-buy window closing.
150 µF, 2.5 V, 150 mOhm — the three numbers that decide rail fit
150 µF capacitance at 2.5 V rated with 150 mOhm ESR — these three specs are the gate for a bulk decoupling or hold-up cap on a low-voltage rail. The 150 mOhm ESR keeps ripple heating manageable.
The molded case and surface-mount 1411 (3528 Metric) footprint let it sit on a standard PCB without special handling.
Molded case, TPS series, general-purpose
Type is Molded, series TPS — KYOCERA AVX's standard low-ESR tantalum platform for power-supply bypass and output filtering. Tolerance is ±20%, which is typical for tantalum electrolytics; the actual capacitance at 2.5 V bias will sit near the nominal 150 µF.
