Product Overview
The DGCX X2 series of metallized polypropylene film capacitors are designed for suppressing electromagnetic interference (EMI) in power supplies. These capacitors feature a non-inductive winding structure with a metallized polypropylene film, a tin-plated copper-clad steel lead, and are encapsulated in a flame-retardant plastic case (UL94V-0) with flame-retardant epoxy resin. They are suitable for interference suppression and X-class circuits where failure of the capacitor would not lead to a risk of electric shock. Key advantages include excellent self-healing properties, high voltage surge capability, and robust construction.
