Capacitance, voltage, and ESR — the BOM-fit check
The TPSB475M025R0700: This is a 4.7 µF ±20% tantalum capacitor rated at 25 V, in the molded TPS series from KYOCERA AVX. The 700 mOhm ESR is the figure that governs ripple current rating and self-heating — for a 12 V rail with 100 mV ripple, the ripple current stays under 140 mA RMS at 25°C before derating.
Package and footprint — 1411 (3528 Metric) size code B
Surface-mount package, 1411 (3528 Metric) case, manufacturer size code B. Dimensions are 0.138" x 0.110" (3.50 mm x 2.80 mm) with a seated height of 0.083" (2.10 mm). The 1210 footprint variant is listed — confirm the pad layout matches your reflow profile; the molded body handles standard convection reflow without moisture sensitivity issues beyond the bake requirement.
This is a standard KYOCERA AVX TPS series part, not a custom or obsolete line. RoHS compliance is standard for the TPS series — no separate certification needed for most production builds. Confirm with your compliance team if the application requires a specific exemption list.
