Product Overview
The MPX X2 series capacitors are designed for electromagnetic interference suppression in power supplies. These metallized polypropylene film capacitors feature a non-inductive winding structure, a flame-retardant plastic case (UL94V-0), and are encapsulated with flame-retardant epoxy resin. They are suitable for interference suppression and X-line capacitor circuits, particularly in applications where the failure of a capacitor would not pose a risk of electric shock. Key features include excellent self-healing properties, high voltage impulse capability, and robust construction.
