* - Capacitor impedance Z is measured at frequency 100 kHz for capacitors CR ≤1 000 µF, and at frequency 10 kHz for capacitors CR > 1 000 µF




Ripple current effective value
versus temperature and frequency can be found from the formula IRO = IR x KT x KF, where

IR- allowable ripple current at 85 °C, 50 Hz (See Table "Capacitor electric parameters")

KT - IR correction factor versus temperature
