The TPSD157M010H0100: This is a 150 µF, 10 V rated molded tantalum capacitor in the 2917 (7343 Metric) package, part of the KYOCERA AVX TPS series. The ±20% tolerance is standard for tantalum; the actual capacitance at the rail voltage will be close to the nominal value because tantalum's DC bias derating is mild compared to MLCC.
The full military temperature range (-55°C to 125°C) means this cap is at home in satellite power buses, downhole instrumentation, or under-hood automotive modules. The molded case and surface-mount 2917 footprint make it a standard pick for boards that see thermal cycling from cold soak to hot soak.
