Capacitors of compact design, polarized, fixed capacity, with radial screw terminals. Capacitor type is used for operation in direct current, ripple and pulse current circuits. The capacitor is available in all-climate (isolated and non-isolated) and temperate/cold climate version (isolated).

It is recommended to use this capacitor type as substitution for capacitors K50-18, K50-27, K50-37, K50-77 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”)
