The TAJB225M020RNJ is a molded tantalum capacitor from the TAJ series, rated at 2.2 µF with ±20% tolerance and a 20 V working voltage. The 3.5 Ohm ESR at 100 kHz sets the ripple current ceiling — in a 20 V rail decoupling application, the self-heating from ripple current must be checked against the temperature derating curve.
