22 µF bulk decoupling for a 12 V bus
The 20 V rating gives 60 % derating on a 12 V rail — enough margin to keep the applied voltage below 80 % of rated voltage, which is the standard reliability guideline for solid tantalum capacitors. The 100 mOhm ESR limits ripple current heating; at 12 V and typical switching-regulator ripple, the self-heating stays within the 125 °C ceiling.
The molded case (2312 / 6032 Metric) measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm — a low-profile footprint for dense PCB layouts.
