At 25 °C ambient, the part can handle a certain ripple current; above 85 °C the voltage derating curve from the TAJ series datasheet applies. For a 25 V rail, a typical design guideline is to derate to 50-60% of rated voltage at 85 °C, which means staying below 12.5-15 V applied across temperature.","metaTitle":"TAJS684K025RNJ KYOCERA AVX Molded Tantalum Capacitor 0.68","metaDescription":"TAJS684K025RNJ KYOCERA AVX TAJ series molded tantalum capacitor, 0.68 µF ±10%, 25 V, 1206 case, 10 Ohm ESR, -55 to +125 °C.
