The -55 to 125°C range covers cold-crank and hot-soak conditions without derating the voltage below the 10 V rating. 100 µF ±10% with 100 mOhm ESR at 100 kHz keeps ripple heating in check for a 10 V rail — the ESR limits the self-heating that would otherwise eat into the 125°C life margin.
Surface-mount footprint, 2312 case
The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm max. Reflow profile follows the standard tantalum curve; the molded body is moisture-sensitive and should be baked per the MSL rating before rework.
