Product Overview
The DGCX X2 series capacitors are designed for suppressing electromagnetic interference (EMI) in power supplies. These metallized polypropylene film capacitors feature a non-inductive winding structure with excellent self-healing properties and high voltage impulse capability. Encased in a flame-retardant plastic shell (PBT) and sealed with flame-retardant epoxy resin, they are suitable for interference suppression and X-class capacitor circuits where failure does not pose a shock hazard. They meet stringent safety certifications including UL, CUL, ENEC-VDE, and CQC.
