This is a solid tantalum electrolytic, molded construction, from the TAJ series — a workhorse for bulk decoupling on 3.3 V or 1.8 V rails where the 4 V ceiling provides 20% derating margin against a 3.3 V rail. ## 1.1 Ohm ESR and 125°C temperature grade ESR is specified at 1.1 Ohm at 100 kHz — this is the effective series resistance that governs ripple current capability and self-heating. For a 220 µF tantalum, 1.1 Ohm is moderate; it will handle tens of milliamps of ripple without excessive temperature rise, but a high-ripple SMPS output may require a lower-ESR polymer or ceramic alternative. At 125°C the rated voltage should be derated per the manufacturer's guidelines — typically 50% of rated voltage for reliable operation above 85°C. Sourced through independent distribution, it is quoted to order against a BOM quantity.","metaTitle":"TAJB227M004SNJ KYOCERA AVX TAJ Series 220 µF 4 V Molded","metaDescription":"TAJB227M004SNJ from KYOCERA AVX: 220 µF, 4 V, ±20% tolerance, 1.1 Ohm ESR, -55°C to 125°C, B case, 1411 (3528 Metric).
