Product Description
Product Overview
The DGCX X2 series of metallized polypropylene film capacitors are designed for suppressing electromagnetic interference in power supplies. These capacitors feature a non-inductive winding structure, good self-healing properties, and the ability to withstand high voltage surges. Encased in a flame-retardant plastic shell with flame-retardant epoxy resin, they are suitable for interference suppression and X-line capacitor circuits where capacitor failure does not pose a risk of electric shock. They are not recommended for use in AC power supply voltage reduction circuits or high-temperature, high-humidity environments.
