220 µF, 16 V, 40 mOhm — bulk decoupling for power rails
The 40 mOhm ESR keeps ripple heating low in switching-regulator output filters and reduces voltage droop during load transients.
The molded case and surface-mount 2917 (7343 Metric) package simplify reflow assembly; the large body size (7.30 mm x 4.30 mm) provides good thermal mass for hand rework under hot air.
