Molded tantalum for bulk decoupling
The TPSC685M020R0700: This is a 6.8 µF, 20 V molded tantalum capacitor from the KYOCERA AVX TPS series, in a 2312 (6032 Metric) case with size code C.
Temperature range and derating
For tantalum capacitors, derating the applied voltage to 50-60% of the 20 V rating is standard practice to reduce field-failure risk from surge current; a 12 V rail is a safe fit.
