KEMET Organic Capacitor (KO-CAP
®
) – Automotive Grade
T591, T598, T597, and T599 High Humidity and High Temperature Automotive Grade Polymer Electrolytic, 2.5 - 50 VDC
Surge Voltage
Surgevoltageisthemaximumvoltage(peakvalue)whichmaybeappliedtothecapacitor.Thesurgevoltagemustnotbe
appliedforperiodiccharginganddischargingincourseofnormaloperationandcannotbepartoftheapplicationvoltage.
Surgevoltagecapabilityisdemonstratedbyapplicationof1,000cyclesatoperatingtemperature.Thepartsarecharged
througha33Ohmresistorfor30secondsandthendischargedthougha33Ohmresistorforeachcycle.
