Product Overview
The DGCX X2 series metalized polypropylene film capacitor is designed for suppressing electromagnetic interference (EMI) in power supply applications. These capacitors feature a non-inductive winding structure with metallized polypropylene film, offering excellent self-healing properties and high voltage surge capability. Encased in a flame-retardant plastic shell (UL94V-0) and sealed with flame-retardant epoxy resin, they are ideal for interference suppression and X-class line-to-line circuits where capacitor failure should not pose a risk of electric shock. Key applications include interference suppressors and across-the-line capacitor circuits.
