This capacitor series is designed specifically for the HID Lighting applications where the capacitors are used as part of the ballast circuit for mercury vapor, metal halide, and high‑pressure sodium lamps. The units are designed to operate at up to 90C, which is the normal requirement for HID ballast capacitors. Due to advances in material technology and breakthroughs in proprietary capacitor manufacturing processes, selected ratings are now available for operation up to 100C for 60,000 Hours.
