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, offering excellent self-healing properties and the ability to withstand high voltage surges. Encased in a flame-retardant plastic shell (UL94V-0) and sealed with flame-retardant epoxy resin, they are ideal for interference suppression and X-line applications where capacitor failure should not pose an electric shock hazard. The product is manufactured by Dongguan Chengxi Electronics Co., Ltd.
