The 50 V rating gives you a 20% derating margin on a 40 V rail, which is the standard practice for tantalum reliability in power-supply filtering. The ESR at the cold end will rise, but the 8 Ohm spec is at room temperature — budget the ESR shift if the application sees -55°C.","metaTitle":"TAJB684K050RNJ KYOCERA AVX 0.68 µF 50 V Molded Tantalum Cap","metaDescription":"TAJB684K050RNJ from KYOCERA AVX — TAJ series, 0.68 µF, 50 V, ±10%, B-case, 8 Ohm ESR, -55°C to 125°C.
