The TAJE477K006RNJ is a molded tantalum capacitor from the TAJ series, delivering 470 µF capacitance at 6.3 V rated voltage in a 2917 (7343 Metric) surface-mount package. With a ±10% tolerance and 400 mOhm ESR, it suits bulk decoupling on low-voltage rails where ripple current and self-heating must be budgeted.
ESR and temperature — the error budget stack
For a 6.3 V rail, the voltage derating rule of thumb means this cap should see reduced DC bias to stay within the safe operating area.
