What this 0603 molded tantalum delivers
The F380J476MMAAXEH3 is a 47 µF molded tantalum capacitor in the 0603 (1608 Metric) case size, rated at 6.3 V with ±20 % tolerance. It belongs to the KYOCERA AVX F38 series, a general-purpose line aimed at space-constrained surface-mount designs where a low-profile (0.90 mm seated height) electrolytic is needed. The 300 mOhm ESR at 100 kHz is the key parametric for ripple-current handling and self-heating — a moderate value that keeps conduction losses in check for decoupling and filtering roles on 3.3 V or 5 V rails.
Temperature endurance and operating envelope
Rated for 1000 hours at 85 °C, the part covers the typical endurance needed for consumer and industrial electronics where the ambient stays below 85 °C. The molded construction (Type Molded) provides mechanical stability and moisture resistance compared to conformal-coated chips, which matters for reflow soldering and board cleaning processes.
