Engineering You
Can Rely On
Self-Healing MPP Film Technology
Metallized polypropylene film automatically isolates dielectric faults through controlled metal vaporization — restoring insulation with negligible capacitance loss. Delivers stable Tan δ and ESR values throughout service life.
Burst-Proof Design
An internal safety mechanism safely separates the capacitor before critical pressure buildup — preventing explosions and fire hazards.
Full IEC, IS & International Compliance
Manufactured and tested to IEC 60831-1+2, IS 13340-1+2, CE, RoHS, and AEC-Q200 standards.
Customizable Sizes & Ratings
All capacitor sizes and ratings available as per customer requirements — from standard panel-mounted units to application-specific designs.
