Aluminum electrolytic capacitor
K50-76

EVAYA.673541.025 TU

Capacitor is used for operation in direct current and ripple current circuits and available in all-climate and temperate/cold climate version. Sealed; isolated and non-isolated in temperate/cold climate version; lacquer coated and non-isolated in all-climate version..

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