Product Overview
The DGCX X2 series capacitors are designed for suppressing electromagnetic interference in power supplies. These metallized polypropylene film capacitors feature a non-inductive winding structure and are encapsulated in a flame-retardant plastic case with flame-retardant epoxy resin. They are suitable for interference suppression and X-class capacitor circuits, particularly in applications where the failure of the capacitor would not pose a risk of electric shock. These capacitors are not recommended for use in R-C voltage divider circuits or high-temperature, high-humidity environments without specific consultation.
