At 125 °C the rated voltage must be derated further per the manufacturer's application note — typically to 2/3 of the 4 V rating for reliable operation at the upper temperature extreme.","metaTitle":"KYOCERA AVX TPSD477M004R0045 Tantalum Cap, 470 µF, 4 V","metaDescription":"KYOCERA AVX TPSD477M004R0045 molded tantalum capacitor, 470 µF, 4 V, 45 mOhm ESR, D-case 2917.
