The TAJD476K025H is a molded tantalum capacitor from the TAJ series, rated at 47 µF and 25 V with ±10% tolerance. The 900 mΩ ESR sets the ripple current handling — for a 100 kHz switching node, the self-heating stays within the part's thermal budget as long as the RMS ripple current is under the rated limit.
Yes, as a tantalum capacitor it is polarized. Observe the polarity marking on the package; reverse voltage damages the part.
