Capacitance, voltage, and ESR — the BOM-fit check
This TPSB476K006S0250 is a 47 µF molded tantalum capacitor rated at 6.3 V with ±10% tolerance.
Package and mounting — 1411 (3528 Metric) surface-mount
Housed in a 1411 (3528 Metric) / 1210 case, measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The B-size code means the 2.10 mm height is the maximum; the actual height may be slightly lower, so clearance under a low-profile shield or adjacent component should be checked against the seated height.
At 125°C, the voltage derating curve in the TPS series datasheet applies — typically a 50% derating is recommended for reliable operation above 85°C. For a 6.3 V part, that means keeping the applied DC voltage below 3.15 V at 125°C to stay within the safe operating area.
This part is in production and suitable for new designs.
