6.8 µF bulk decoupling with 25 V headroom
The TPSC685K025R0500 is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated 6.8 µF at 25 V with ±10% tolerance. The 500 mOhm ESR at 25 °C sets the ripple current capability: for a typical 100 kHz buck converter output, the I²R self-heating at the rated ripple current keeps the internal temperature rise under 10 °C, leaving margin for ambient up to 105 °C without exceeding the 125 °C limit.

The molded case (C case, 2312 / 6032 metric) measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm — a standard footprint for bulk decoupling on dense PCBs.
