The MOV 20D Series Metal Oxide Varistors are designed for high-power circuits and harsh surge environments, offering excellent energy absorption and superior surge current endurance. Suitable for protection in AC mains, power filters, SMPS, and motor drives, this series features both K (standard) and KJ (reinforced lead) types to handle mechanical stress and high surge conditions. With varistor voltages ranging from 180V to 1120V, the 20D series ensures reliable overvoltage protection for global industrial applications.
The MOV 20D Series is widely used for high-energy surge protection in:
