Tyco Electronics / Raychem Radial-Leaded Metal Oxide Varistor Devices

Raychem Circuit Protection’s Radial-Leaded Metal Oxide Varistor (ROV) devices help to provide protection from overvoltage faults such as lightning, power contact, and power induction for a wide variety of power systems. The devices are suitable for a broad range of applications, including, but not limited to: security systems, power supplies, surge strips, motors and telecommunications equipment. The ROV devices help to protect valuable equipment for potential power surge damage by clamping high-energy, short-duration impulses. They also have high current handling and energy absorption capability and fast response times to help protect against transient faults.

The ROV overvoltage protection devices expand Raychem Circuit Protection's portfolio and can offer the circuit board designer a complete overcurrent/overvoltage solution. For example, pairing an ROV device with Raychem Circuit Protection's PolySwitch™ LVR overcurrent protection devices can help provide a completely resettable circuit protection solution for power suppliers, surge strips and control board transformers. In addition, ROV devices can be combined with PolySwitch devices to help provide protection for electric motors, telecommunications equipment, and various other systems.
