Self-healing Ac Filter Capacitor

The ASMJ series self-healing AC filtering capacitors are mainly used in power frequency AC power systems to form filtering circuits with other components, filter out fundamental or multiple harmonic currents in the system, and can also serve as reactive power compensation to improve power factor.

This product uses metalized polypropylene film with excellent self-healing performance as the solid medium, and is produced using the most advanced production technology internationally. The product has high reliability, small size, low loss, and excellent electrical performance.
