Product Description
Product Overview
The DGCX X2 series are metallized polypropylene film capacitors designed for suppressing electromagnetic interference in power supplies. These capacitors feature a non-inductive winding structure with self-healing properties, capable of withstanding high voltage surges. They are encapsulated in a flame-retardant plastic case (PBT) and epoxy resin, meeting UL94V-0 standards. Ideal for interference suppression circuits and X-class applications where capacitor failure should not pose a shock hazard. Not recommended for capacitive power supplies or high-temperature/high-humidity environments.
