22 µF, 16 V, 400 mOhm ESR — molded tantalum for power-rail bulk decoupling
The 400 mOhm ESR is the key thermal parameter: at ripple current, the I²R loss heats the part, and the ESR value sets the self-heating ceiling.
This cap can sit on an avionics power supply that sees cold-soak and full-load temperatures without exceeding the rated envelope. The molded construction provides mechanical stability across the thermal cycle.
1411 (3528 Metric) case — B-size footprint
Housed in the 1411 (3528 Metric) case with manufacturer size code B, the part measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm.
