47 µF, 10 V — molded tantalum for decoupling and hold-up
The TPSB476M010P0500 is a 47 µF, 10 V molded tantalum capacitor from the KYOCERA AVX TPS series, in the B case size (1411 / 3528 Metric). The molded case provides consistent mechanical protection and a flat top for pick-and-place handling.
Listed as Active on the lifecycle record.
500 mOhm ESR — what it drives in the power rail
For a 100 kHz buck converter output, the capacitor's self-heating is I_ripple² × ESR — keep the RMS ripple current below the manufacturer's recommended limit to stay inside the thermal envelope. The molded package and wide temperature range help, but the ESR is the bottleneck for high-ripple applications.
