The 300 mOhm ESR is moderate for this capacitance; it keeps ripple-current self-heating manageable in a 2 A step-down converter output filter. This cap sits on a satellite power bus that sees -40°C on the dark side and 85°C in direct sunlight, with margin at both ends. The molded case (Type Molded) handles the thermal cycling without cracking the anode connection — a common failure in conformally-coated boards that go through reflow multiple times. Active product status — KYOCERA AVX is still running the TAJ series, so no last-time-buy deadline on this order code.","metaTitle":"TAJY227M004RNJ KYOCERA AVX 220 µF 4 V Molded Tantalum","metaDescription":"TAJY227M004RNJ 220 µF ±20% 4 V molded tantalum capacitor, 300 mOhm ESR, -55°C to 125°C, 2917 (7343 Metric) package.
