What this molded tantalum capacitor delivers on the rail
The TPSD107K010R0150 is a 100 µF molded tantalum capacitor from KYOCERA AVX's TPS series, rated at 10 V with ±10% tolerance and a 150 mOhm ESR. The D case (2917 metric, 7.30 mm x 4.30 mm x 3.10 mm max seated height) is a common footprint for power supply decoupling in telecom and industrial DC-DC converters.
Operating range and deployment context
The molded construction provides mechanical stability and moisture resistance compared to conformally coated parts. For a 10 V rated tantalum, a 50% voltage derating (5 V max applied) is standard practice to avoid surge failures; the TPS series is a general-purpose grade, not a low-surge or automotive AEC-Q200 series.
The TPS series includes multiple voltage/case combinations; if the exact 10 V D case is on allocation, a same-case higher voltage rating (e.g., 16 V) with the same footprint can be cross-referenced, but capacitance and ESR will differ — confirm the substitution with the design team.
