4.7 µF, 10 V, 300 mOhm ESR — molded tantalum in 0805
The F381A475MSA is a molded tantalum capacitor from the KYOCERA AVX F38 series, delivering 4.7 µF capacitance with ±20% tolerance at a rated voltage of 10 V. The 0805 case (2.00 mm x 1.25 mm footprint, 0.90 mm seated height) fits standard pick-and-place lines and matches the common 0805 land pattern.
Temperature range and endurance — -55°C to 105°C, 1000 hours at 85°C
The operating temperature span of -55°C to 105°C covers industrial control, outdoor telecom, and under-hood automotive auxiliary circuits. The rated lifetime of 1000 hours at 85°C is typical for tantalum chips — if the capacitor sits near a hot regulator or processor, derate the voltage or add a thermal gap to avoid early wear-out. The molded construction provides better moisture resistance than dipped tantalums, but the reels should still be stored dry (MSL handling per the datasheet).
