Product Overview
The DGCX MX2 series X2 metallized polypropylene film capacitors are designed for suppressing electromagnetic interference in power supplies. These capacitors feature a non-inductive winding structure with metallized polypropylene film and are encapsulated in a flame-retardant plastic case (UL94V-0) with flame-retardant epoxy resin. They are suitable for interference suppression and X-line circuits, particularly in applications where capacitor failure would not pose a risk of electric shock. Key advantages include good self-healing properties, high voltage impulse tolerance, and robust construction.
