This F380J226MSAAH1 is a 22 µF molded tantalum capacitor rated at 6.3 V, housed in an 0805 (2012 metric) surface-mount package. The 150 mOhm ESR at 100 kHz keeps ripple heating under control in switching regulator output filters — a key parameter for low-voltage, high-frequency POL converters where ceramic-only decoupling might ring.
Temperature range and endurance
The 1000-hour endurance at 85°C is the standard tantalum qualification — expect useful life well beyond that at lower temperatures.
Molded construction gives a flat top for pick-and-place and consistent solder joint standoff.
KYOCERA AVX continues production of the F38 series.
