The F380K476MSA is a 47 µF molded tantalum capacitor from KYOCERA AVX's F38 series, rated at 8 V with ±20% tolerance. The molded construction gives it a stable, rectangular body that sits well in automated pick-and-place and reflow processes. It comes in an 0805 (2012 metric) package — 2.00 mm x 1.25 mm footprint, 0.90 mm seated height — and operates from -55°C to 105°C. That temperature range covers most industrial and automotive cabin environments, though the 1000-hour lifetime at 85°C means you need to check the ripple current and ambient temperature against the application's expected service life. It tells you the capacitor can handle moderate ripple current at switching frequencies common in DC-DC converters, but the ESR also sets a floor on how much the output voltage will sag under transient load.
Why the NRND status matters for your BOM
For a new design, you should qualify an alternative before committing the BOM. For an existing board that already uses this part, the NRND flag means you have time to source remaining lifetime buys or identify a second-source molded tantalum in the same 0805 footprint and voltage rating. The ±20% tolerance is wide enough that most general-purpose 47 µF / 8 V molded tantalums from other brands will fit electrically, but confirm the ESR and ripple current rating against your circuit.
