15 µF, 25 V — power rail decoupling in a molded case
The TPSD156K025S0100: This is a molded tantalum capacitor in the TPS series from KYOCERA AVX, rated 15 µF at 25 V with ±10% tolerance and 100 mOhm ESR.
Active production — no lifecycle concern
The TPS series is a general-purpose molded tantalum line; this part number is a standard catalog item, not a custom or last-time-buy code.
Full military temperature span
For a tantalum capacitor, the voltage derating at 125°C should be applied per the manufacturer's guidelines — a 25 V rated part typically sees 50 % derating above 85°C, so budget 12.5 V max at the high end.
