Product Overview
The DGCX X2 series is a metallized polypropylene film capacitor designed for suppressing electromagnetic interference (EMI) in power supplies. These capacitors feature a non-inductive winding structure, excellent self-healing properties, and the ability to withstand high voltage surges. Encased in a flame-retardant plastic shell and epoxy resin, they are suitable for interference suppression and X-class capacitor circuits where failure would not pose a risk of electric shock. They are not recommended for use in capacitive power supplies or high-temperature, high-humidity environments without prior consultation.
