100 µF, 16 V, 200 mOhm ESR — what this means on the power rail
At 100 kHz, a 200 mOhm ESR with 100 µF gives an impedance of roughly 200 mOhm — the ESR dominates over the capacitive reactance (~16 mOhm), so the ripple voltage is essentially I_ripple × 0.2 Ω. For a 1 A ripple current, that is 200 mV of ripple across the cap.
Full military temperature range — deployment fit
The molded case and surface-mount 2312 (6032 Metric) footprint keep the board assembly process standard — no special handling beyond the usual tantalum voltage derating (typically 50% for aerospace).
Active production — no EOL clock ticking
The part can be designed into a new BOM today without worrying about a forced migration mid-production.
