Bulk capacitance for a 6.3 V rail
The TPSB476K006S0500 is a 47 µF molded tantalum capacitor from the KYOCERA AVX TPS series, rated at 6.3 V with ±10% tolerance. The 500 mOhm ESR is moderate for this capacitance value, meaning it handles ripple currents typical of general-purpose decoupling on a 6.3 V supply rail without excessive self-heating.
Supplied in a B case (1411 / 3528 Metric, also referenced as 1210) with dimensions 3.50mm x 2.80mm and a seated height of 2.10mm max. The surface-mount land pattern is standard for this case size and routes cleanly on a 2-layer PCB.
