The F380J226MMAAH1 is a 22 µF ±20% molded tantalum capacitor rated at 6.3 V from KYOCERA AVX's F38 series. The 200 mOhm ESR at 100 kHz is the headline spec for a part this small — it keeps ripple heating under control in DC-DC output filtering or local decoupling for a 1.8 V or 3.3 V rail. At 22 µF, it is a common bulk cap value for a moderate-load POL converter.
Temperature range and lifetime — where it runs without derating
The 1000-hour lifetime at 85°C is a standard tantalum endurance figure — expect longer life at lower ambient temperatures, but the 105°C upper limit is the real design margin for hot spots near a regulator or processor.
