The F380J686MSALZT: The 200 mOhm ESR at 100 kHz keeps ripple voltage low on a switching regulator output; paired with the 0805 footprint, it fits tight layout budgets.
Temperature and endurance trade-offs
Rated for 1000 hours at 85°C, this cap's lifetime is typical for a molded tantalum — running it at lower temperature with voltage derating can extend service life beyond the rated endurance.
