Aluminum electrolytic capacitor

elecond-market@elcudm.ru
+7 (34147) 2-99-89
Конденсатор К50-85
AZHYAR.673541.014 ТУ
Capacitor is used for operation in direct current and ripple current circuits, secondary power sources and converter equipment. Capacitor is available in all-climate version. Sealed, polar, constant capacity, with axial wire leads. Isolated.

It is recommended to use this capacitor type as substitution for capacitors K50-24, K50-29, K50-20 types.

* 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
