That voltage margin covers 12 V, 24 V, and 48 V rails with healthy derating — a 50 V part on a 12 V bus gives 4× headroom against surge and ripple. ## ESR and temperature grade for circuit design In a low-impedance rail, the ESR dominates the AC loss — a 100 kHz ripple of 100 mA dissipates 80 mW, which the molded case must sink without exceeding the 125 °C limit.","metaTitle":"TAJB684M050RNJ KYOCERA AVX 0.68 µF Molded Tantalum","metaDescription":"TAJB684M050RNJ from KYOCERA AVX: 0.68 µF, 50 V, ±20%, molded tantalum, 8 Ohm ESR, -55 to 125 °C.
