The TAJE477K004RNJ is a 470 µF molded tantalum capacitor rated at 4 V with ±10% tolerance, housed in the 2917 (7343 Metric) case size (EIA code E). Its 500 mOhm ESR at 100 kHz is the figure that determines ripple current capability and self-heating — at 470 µF the ESR is the limiting factor for AC ripple, not the capacitance itself.

Frequently asked questions
What is the ESR of TAJE477K004RNJ?
500 mOhm maximum at 100 kHz. This ESR is the key parameter for ripple current — at 470 µF the capacitor can handle roughly 0.7 A ripple at 85°C before self-heating becomes a concern.
