LCRR07D Series

Medium-Size High Energy Varistor for Surge Protection in Power, Lighting, and Home Appliance Systems

The MOV 07D Series Metal Oxide Varistors (K and KJ types) are mid-sized overvoltage suppression devices designed for medium-energy surge protection. Compared to the 05D series, the 07D series offers higher surge capability and broader application adaptability. The K version features standard leads, while the KJ version provides reinforced leads for improved surge endurance. With fast response, high non-linearity, and low leakage current, these varistors are ideal for transient voltage suppression in various electrical and electronic systems.

The MOV 07D Series is widely used in the following applications for surge suppression:

  • Switching power supplies and adapter inputs

  • LED drivers and intelligent lighting systems

  • White goods appliance controllers (microwave ovens, induction cookers, washing machines)

  • Power interfaces for security and monitoring systems

  • Smart switches, energy meters, and relay protection

  • Communication equipment and RJ45 port protection
