22 µF, 35 V, 500 mOhm ESR — bulk decoupling for 12-24 V rails
The 500 mOhm ESR at 100 kHz sets the ripple current capability and output voltage ripple in a switching converter — for a 100 kHz buck converter drawing 500 mA ripple current, the self-heating from ESR stays under 125 mW, well within the part's thermal budget. The 2917 (7343 Metric) case size with E code means the part occupies 7.30 mm x 4.30 mm of board area, seated at 4.30 mm max height — a common footprint for bulk capacitance in space-constrained power stages.
The molded case provides mechanical stability across the thermal cycle without the moisture sensitivity of conformal-coated chips.
