AZHYAR. 673541.012 TU

Low impedance capacitors with radial wire leads. The design of the capacitors is sealed. 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”)
