The TPSC106K025S0500: No need to stockpile or hunt surplus — this BOM line stays available for new builds and service spares alike.
10 µF at 25 V — the decoupling sweet spot
10 µF capacitance at 25 V rated voltage gives you margin above a typical 10 V rail to absorb transients. The ±10% tolerance keeps the effective capacitance predictable across the reel. 500 mOhm ESR at 25°C means this part handles ripple current without excessive self-heating. For a buck converter output, that ESR dominates the output ripple voltage — budget it into your noise budget before layout.
Molded case, size code C — footprint fit check
The 6.00 mm x 3.20 mm footprint and 2.80 mm seated height fit standard reflow profiles. No exposed paddle means the land pattern is straightforward — just the two terminations and a keep-out zone for the moulding radius.
The TPS series is a general-purpose grade — no AEC-Q200 automotive qualification, so for under-hood use, cross-check the KYOCERA AVX automotive line.
