68 µF at 25 V — bulk decoupling for 12 V and 5 V rails
The TPSV686K025R0080: The 80 mOhm ESR is the figure that governs ripple current handling and self-heating in the 2924 case — a lower ESR means less temperature rise under the same AC ripple, which directly affects long-term reliability in a power rail filter. The 25 V rating provides healthy derating on a 12 V rail (roughly 48% margin) and adequate headroom on a 5 V rail.
Case size, footprint, and temperature range
This is a standard tantalum footprint — the pad layout matches the EIA 2924-18 pattern, and the V code tells you the case height band without checking the drawing. The capacitance and ESR are specified across this range; expect the ESR to rise at low temperature and the leakage to increase above 85 °C.
