The 20 Ohm ESR at 20 V sets the ripple current ceiling and the self-heating under AC load — for a 1 µF part in a 3.3 V rail filter, the impedance at 1 MHz is dominated by the ESR, not the capacitive reactance. ## Active production — no end-of-life watch This covers avionics, downhole instrumentation, and outdoor telecom where the ambient swings across the entire range. The 20 Ohm ESR is specified at room temperature; ESR rises at cold temperature and falls at high temperature, which shifts the filter corner frequency and the ripple current capability across the operating envelope.","metaTitle":"TAJR105M020RNJ KYOCERA AVX 1 µF 20 V Molded Tantalum","metaDescription":"TAJR105M020RNJ molded tantalum capacitor, 1 µF ±20%, 20 V rated, 20 Ohm ESR, -55 to +125 °C, 0805 case.
