10 µF, 20 V, 700 mOhm ESR — TPS series molded tantalum
The TPSC106K020R0700: This is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated 10 µF at 20 V with ±10 % tolerance and 700 mOhm ESR. The 20 V rating on a 10 µF cap gives enough headroom to derate by 50 % on a 12 V rail — standard practice for solid tantalums to keep the failure rate low. 700 mOhm ESR is the figure a power designer checks against the ripple current in a buck converter output — higher ESR means more self-heating at the same ripple, so the cap's temperature rise stays within the 125 °C ceiling.
Case C footprint and full temp range
Manufacturer size code C (2312 / 6032 metric) — 6.00 mm x 3.20 mm x 2.80 mm max seated height — is a common tantalum footprint that drops into existing PCB layouts without a pad change. Rated -55 to +125 °C, so it handles avionics, downhole logging, or satellite thermal cycling without a commercial-grade restriction.
