The TAJY477K002RNJ is a molded tantalum capacitor from the TAJ series, rated at 470 µF with a ±10% tolerance and a 2.5 V working voltage. The 200 mOhm ESR is the figure that determines ripple current handling and self-heating — for a 470 µF bulk cap on a 2.5 V rail, that ESR keeps the temperature rise within the molded-case limits under typical decoupling loads.
