The TAJE476K025YNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, 47 µF ±10% at 25 V, in the E case size (2917 / 7343 metric).
The 900 mOhm ESR sets the self-heating limit under AC ripple — at 100 kHz the capacitor dissipates I² × 0.9 W per amp of ripple current. Above about 500 mA ripple, the internal temperature rise starts eating into the 125 °C ceiling, so derate accordingly.
The evidence does not carry a RoHS compliance statement for this order code. Confirm the specific date-code lot at quote time.
The TAJ series includes many 47 µF, 25 V parts in the E case with different ESR and tolerance grades. A direct drop-in would be another TAJ E-case with the same capacitance, voltage, and tolerance — confirm the ESR and temperature range against your derating requirement.
