Rated at 6.3 V, it is suited for decoupling and filtering on low-voltage rails — 3.3 V, 1.8 V, or 1.2 V supplies — where the 1.5 Ohm ESR at 100 kHz provides a known impedance floor for ripple attenuation. For a BOM that already uses this capacitor, sourcing through authorized distribution is the cleanest path: we can quote to order against your quantity. If you are starting a new design, KYOCERA AVX recommends selecting an active-series alternative — the F38 series has no direct successor listed, so check the current F38 or F39 series datasheets for a pin-compatible drop-in with similar ESR and voltage rating. At 6.3 V rated voltage, a 50% derating guideline (typical for tantalum) keeps the applied voltage under 4.2 V for reliability. The molded construction provides consistent mechanical dimensions and good moisture resistance compared to uncoated chips. Lifetime is specified at 1000 hours at 85°C — typical for tantalum capacitors. Derating the applied voltage and keeping the ambient below 85°C extends useful life well beyond the rated endurance.","metaTitle":"F380J105MUA KYOCERA AVX Molded Tantalum Capacitor 1 µF 6.3","metaDescription":"F380J105MUA from KYOCERA AVX: Molded tantalum capacitor, 1 µF ±20%, 6.3 V, 0402 case, 1.5 Ohm ESR.
