If you are qualifying a fresh board, look for a current-series alternative — the F38 series itself may have a follow-on part with a similar footprint and rating. This is a 4.7 µF molded tantalum rated at 30 V with a 500 mOhm ESR at 100 kHz. The 30 V rating gives headroom on a 12 V or 24 V rail — tantalum caps need voltage derating, so 30 V lets you run at 20 V continuous without stressing the dielectric. The 500 mOhm ESR is moderate; it limits ripple current to roughly 300 mA RMS before self-heating becomes a concern. In a switching regulator output, that ESR also sets the output ripple voltage — check the ripple current in your design against the cap's dissipation limit. ## 0805 package, surface-mount, tape-and-reel 0805 (2012 metric) — a common footprint that rework techs can handle with a standard soldering iron. The package is molded, so polarity marking is visible on the top. It ships on tape and reel or cut tape, so small-quantity orders are straightforward. ## Temperature range and lifetime Rated for -55°C to 105°C, which covers most industrial and outdoor environments. The lifetime spec is 1000 hours at 85°C — that is the endurance test condition. If your application runs at 85°C continuously, the cap is good for about 1000 hours. Above 85°C, derate the voltage further and expect shorter life.","metaTitle":"F381S475MSA 4.7 µF 30 V Molded Tantalum Capacitor NRND","metaDescription":"F381S475MSA from KYOCERA AVX — 4.7 µF, 30 V, 0805, ±20%, 500 mOhm ESR.
