150 µF at 4 V — bulk decoupling for a low-voltage rail
The 400 mOhm ESR sets the self-heating floor: at 150 µF and 4 V, the ripple current rating is limited by that resistance. A switcher output with 100 kHz ripple sees I²R losses that drive the core temperature above ambient — keep the RMS ripple below the datasheet curve.
Full military temperature range — avionics and downhole fit
The 2917 (7343 Metric) case is a standard footprint — 7.30 mm x 4.30 mm, seated height 2.00 mm max. It reflows on a standard lead-free profile; the molded body handles the thermal shock of a 260 °C peak without cracking, but a slow ramp above 150 °C helps avoid stress on the tantalum anode.
