+7 (34147) 2-99-89
Конденсатор К50-77
EVAYA.673541.013 TU
Capacitors are used in power converter technology, frequency converters, rectifiers, etc.
Capacitors are suitable for application in direct current and ripple 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 K50-37, K50-18 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”)
