Product details

The TAJW227K004RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 220 µF at 4 V with ±10% tolerance. The 2312 (6032 Metric) case fits standard pick-and-place reels and is a common footprint for board-level energy storage or bulk decoupling where the voltage rail stays below 4 V.

In a low-frequency smoothing or hold-up capacitor role the dissipation stays manageable, but in a high-ripple switching regulator output this part will self-heat more than a low-ESR polymer would.

Frequently asked questions

Is TAJW227K004RNJ polarized?

Yes, like all tantalum capacitors, the TAJW227K004RNJ is polarized. The positive lead is marked on the case. Reversing the voltage will damage the part.
