Capacitance, voltage, and package
This TAJA474K025RNJ is a 0.47 µF tantalum capacitor rated at 25 V, in a molded 1206 (3216 Metric) package.
ESR and temperature range
The 14 Ohm ESR at 25 V rating means this part handles moderate ripple current but is not suited for high-frequency switching supplies where lower ESR (sub-1 Ohm) is needed.
