A Dry Film Solution for Electrolytic Capacitor Replacement

UNLYTIC® technology provides a dry film solution for electrolytic capacitor replacement, offering ten (10) times the current density and three (3) times the over voltage protection. For safety, eliminates the possibility of caustic electrolyte leakage and its harmful effects to the environment.

This capacitor is designed for switching power supplies where high voltages at elevated temperatures are needed. The component is designed to perform under conditions of high peak current and dv/dt without impact to long term reliability. The housing has integrated standoffs molded in. They help to support the component to withstand elevated shock and vibration conditions.
