Aluminum electrolytic capacitor
K50-68

EVAYA.673541.003 TU
AZHYAR.673541.005 TU

Capacitors are suitable for application in direct current, ripple current and pulse current circuits. Capacitors are produced in all climate version and temperate/cold climate version.

It is recommended to use this capacitor type as substitution for capacitors K50-35, K50-38, K50-6 types.
