The TAJD475K035SNJ is a molded tantalum capacitor from the TAJ series, delivering 4.7 µF capacitance at 35 V rated voltage with ±10% tolerance. Its 1.5 Ohm ESR at 100 kHz sets the ripple current ceiling — in a buck converter output filter, that ESR contributes directly to the output ripple voltage and self-heating, so the derating curve in the datasheet matters for reliability above 85°C.
It comes in the 2917 (7343 Metric) surface-mount case, which corresponds to manufacturer size code D.
The equivalent series resistance is 1.5 Ohm measured at 100 kHz.
