Aluminum electrolytic capacitor
K50-83

AZHYAR. 673541.012 TU

Capacitor is used for operation in direct current and ripple current circuits, secondary power sources and converter equipment. Capacitor is available in all-climate and temperate/cold climate version. Sealed; isolated.

It is recommended to use this capacitor type as substitution for capacitors K50-15, K50-27 (the second variant), K50-29, K50-32, K50-32A, K50-33A, K50-68 types.

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")
