Molded tantalum, 47 µF, 10 V — 0805 footprint
The F381A476MSALZT is a molded tantalum capacitor from the KYOCERA AVX F38 series, rated at 47 µF with a 10 V working voltage and ±20% tolerance. The 0805 case (2.00 mm x 1.25 mm footprint, 0.90 mm seated height) fits tight PCB layouts where board real estate is at a premium.
This means KYOCERA AVX has flagged the part for eventual discontinuation; it remains available for existing BOM lines but should not be selected for new projects. Buyers should confirm current availability and lead time at quote time, as supply may tighten without notice. For new designs, a direct replacement within the F38 series or a functionally equivalent molded tantalum in the same 0805 case with matching capacitance, voltage, and ESR should be evaluated.
PCB layout — 0805 pad geometry and profile
The 0805 (2012 metric) case measures 2.00 mm x 1.25 mm with a seated height of 0.90 mm. Standard 0805 solder pad dimensions apply; the low profile suits height-constrained assemblies. The molded body provides mechanical robustness during reflow and handling. Operating temperature spans -55°C to 105°C, with a rated lifetime of 1000 hours at 85°C. For applications requiring extended life above 85°C, derating the applied voltage or selecting a higher-temperature-rated tantalum series is advised.
