10 µF at 25 V — Molded tantalum for high-temp BOM positions
The TPSB106K025T1800 is a 10 µF, 25 V molded tantalum capacitor from KYOCERA AVX's TPS series, in the standard 1411 (3528 Metric) case size. The ±10% tolerance covers most decoupling and bulk storage roles on a mixed-signal board. The 1.8 Ohm ESR at 100 kHz is moderate for a 10 µF tantalum; it limits ripple current before self-heating cuts into the 2000-hour lifetime budget.
Lifetime is specified as 2000 hours at 125°C with rated voltage applied. In a lower ambient, the expected life increases per standard derating rules. The TPS series is marked as General Purpose, so there is no low-ESR or automotive-grade screening. For engine-bay or chassis-mounted applications that see sustained 125°C, confirm the ripple current stays within the derating curve.
