The TPSD227K010H0150: 220 µF at 10 V — the capacitance and voltage cover the bulk decoupling need for a power rail with derating margin on the voltage. The 150 mOhm ESR limits self-heating, so the cap runs cool in a power-supply output filter or a processor VDD bank.
Case size and board fit
D case (2917 / 7343 Metric) — 7.30 mm × 4.30 mm footprint, 3.10 mm seated height. The molded rectangular body sits flush on the PCB; no lead forming needed.
This cap is at home in avionics power buses, satellite payload decoupling, and downhole instrumentation that sees 125°C ambient. The molded case and tantalum dielectric hold the capacitance within ±10% across the full band.
No pin-compatible second source or successor is listed, but the TPS series is a standard molded tantalum family with wide cross-reference availability.
