Product Overview

The MPX X2 series metallized polypropylene film capacitors are designed for suppressing electromagnetic interference in power supplies. These capacitors feature a non-inductive winding structure, excellent self-healing properties, and the ability to withstand high voltage surges. They are encapsulated in a flame-retardant plastic case and epoxy resin, meeting UL94V-0 standards. Typical applications include interference suppression circuits and X-class capacitor circuits, suitable for use in situations where capacitor failure does not pose a risk of electric shock. They are certified by UL&CUL, ENEC-VDE, and CQC.
