The TPSB476K010R0500: 500 mOhm ESR at 25°C sets the ripple current ceiling and the self-heating under AC load — for a 100 kHz switching regulator output, this ESR keeps the ripple voltage under 50 mV at 100 mA ripple current.
Package and footprint — what lands on the pad
Listed for both 1411 (3528 Metric) and 1210 footprints — the 3.50 mm x 2.80 mm body with 2.10 mm seated height fits either land pattern without a layout change. Surface-mount molded case, supplied on tape and reel or cut tape — the BOM quantity drives the reel selection; cut tape suits prototype or low-volume builds.
The TPS series is a general-purpose molded tantalum line from KYOCERA AVX — no direct pin-compatible second source confirmed, but functional equivalents exist from other manufacturers with the same 1411/1210 footprint and 10 V rating.
