The 1.4 Ohm ESR at 100 kHz is the spec that governs ripple current capability — for a 100 kHz buck converter output, that ESR limits the self-heating to about 70°C rise at the maximum ripple current, so the 125°C rated temperature still leaves margin in a hot enclosure. Packaged in a 1411 (3528 Metric) surface-mount case, size code B, measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm.
