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	100
KT	2.1	2.04	1.98	1.9	1.73	1.5	1.0

KF - IR correction factor versus frequency

F, Hz	50	100	300	600	1 000	10 000	≥50 000
KF	1.0	1.25	1.5	1.63	1.69	1.88	2.0
