Product Overview

The DGCX X2 series capacitors are metallized polypropylene film capacitors designed for suppressing electromagnetic interference in power supplies. Featuring a non-inductive winding structure and self-healing properties, these capacitors offer high voltage impulse resistance and are encapsulated in UL94V-0 flame-retardant plastic casings with epoxy resin. They are widely used in interference suppression and X-class capacitor circuits where capacitor failure should not pose an electric shock hazard. This series is not suitable for capacitive power supplies or high-temperature/high-humidity environments.
