Product details

220 µF at 4 V in a B-size molded case

The B-size code corresponds to the 1411 (3528 Metric) / 1210 footprint — 3.50 mm x 2.80 mm, seated height 2.10 mm max. That 1.1 Ohm ESR sets the ripple-current ceiling: for a given ripple, the I²R self-heating is fixed, so a lower-ESR replacement would run cooler in the same spot.

The molded case is general-purpose, not hermetically sealed, so conformal coating is advisable in condensing environments.

Listed as Active — no EOL notice, no last-time-buy clock. The TAJ series is a long-running standard; KYOCERA AVX continues production.

Frequently asked questions

Is TAJB227M004RNJ RoHS compliant?

The part is listed as general-purpose and carries no RoHS exemption flag in the record. Standard KYOCERA AVX tantalum production is RoHS-compliant; confirm with the date-code-specific certificate if your compliance audit requires it.
