Product details

Bulk decoupling for 25 V rails

It sits on a 25 V rail — the 47 µF value provides enough charge storage to absorb transient current demands from an adjacent switching regulator or a microcontroller's I/O bank. The 900 mOhm ESR limits ripple current heating; for a 100 kHz buck converter output, the ripple current rating of this capacitor should be checked against the converter's inductor ripple to stay within the part's thermal limits.

The molded case and surface-mount 2917 package keep the part stable across thermal cycling, but the ESR will rise at cold temperatures — derate the ripple current at -55°C per the manufacturer's curve.

Frequently asked questions

Is TAJE476K025RNJ RoHS compliant?

The evidence does not list a RoHS compliance status. For RoHS certification, refer to the manufacturer's datasheet or contact KYOCERA AVX directly. We can also check the date code and lot-specific compliance at RFQ.

What is the closest alternative to TAJE476K025RNJ in the TAJ series?

Within the TAJ series, a direct alternative would share the same 47 µF, 25 V rating, ±10% tolerance, and 2917 (E case) package. Other manufacturers' tantalum capacitors with matching ratings and case size may be functionally equivalent, but pin compatibility is not guaranteed — confirm the footprint and ESR before substituting.
