NRND — plan your BOM around this
The F381A106MMAAH1 carries a Not Recommended for New Designs (NRND) status from KYOCERA AVX.
Core ratings for filter and decoupling duty
10 µF capacitance at 10 V rated voltage in a 0603 molded case — that is a compact energy reservoir for rail decoupling on a 3.3 V or 5 V supply. The ±20% tolerance is typical for tantalum; budget for the low side in your ripple calculation. ESR is specified at 300 mOhm at 100 kHz.
Temperature range and reflow fit
The 1000-hour endurance at 85°C is standard for tantalum — derate voltage for longer life above 85°C. The 0603 footprint is pick-and-place friendly, but molded tantalum has a higher MSL sensitivity than ceramic MLCCs.
