* 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

Tenv, °C	25	40	50	60	70	85	125
KT	1.3	1.21	1.15	1.07	1.0	0.87	0.67

KF - IR correction factor versus frequency

F, Hz	50	100	300	600	1 000	10 000	≥50 000
KF	1	1.25	1.5	1.63	1.69	1.88	2.0
