47 µF bulk decoupling with a 500 mΩ ESR ceiling
The 500 mΩ ESR is the ceiling for self-heating under ripple current — a lower ESR means less temperature rise inside the part, which directly improves reliability in a warm enclosure.
Full military temperature range in a surface-mount case
That means it is a fit for avionics black boxes, satellite power buses, or downhole instrumentation where the ambient cycles from cold soak to internal heat rise. The case C (2312) footprint is 6.00 mm × 3.20 mm with a seated height of 2.80 mm — a common size that fits standard pick-and-place nozzles and reflow profiles.
