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.","metaTitle":"TAJB227M004RNJ – KYOCERA AVX 220 µF 4 V Molded Tantalum","metaDescription":"TAJB227M004RNJ: 220 µF, 4 V, ±20% tolerance, 1.1 Ohm ESR, -55°C to 125°C.
