Capacitance, voltage, and ESR for power rail filtering
The TPSD227K010Y0150: Rated 220 µF at 10 V with ±10% tolerance, this TPS series molded tantalum capacitor delivers 150 mOhm ESR — the ESR figure directly sets the ripple current capability and self-heating under AC load, so it is the number to check against the power rail's ripple budget.
