TVS - Varistors, MOVs are surge arresting devices that provide a safe path to ground when an abnormal surge of current occurs. The ROV14H680K-S is a varistor optimized for automotive applications, and can be used in other applications as well.

The ROV14H680K-S protection devices are designed to rapidly clamp transient voltages and reduce overvoltage stress on sensitive electronic components. The device features a ceramic disc housed in a rugged plastic outer case, along with two soldered lead wires. The lead wires are each connected to a separate terminal and can be installed in serial, parallel, or temperature compensated circuit configurations. The disc is comprised of zinc oxide and rolled steel forming a bimorph structure.

The working principle of a ROV14H680K-S is similar to other varistors in that it clamps voltage and current when exposed to abnormal voltage transients by conducting current to ground. When the surge voltage is lower than the breakdown voltage, the bimorph structure remains open and does not conduct. When the voltage transient exceeds the breakdown voltage of the device, the varistor may be driven into conduction and begin to conduct current and clamp the voltage to the rated clamping voltage of the device.

ROV14H680K-S varistors have found widespread usage in applications where overvoltage protection of electronic components is necessary. They are frequently used in automotive components such as airbag electronics, anti-theft systems, air conditioning systems, and engine control systems. Additionally, they can also be used in other applications such as UPS systems, industrial automation control systems, and communication equipment.

Overall, the ROV14H680K-S is a versatile varistor that can provide excellent overvoltage protection for a variety of applications in the automotive and other industries. Its rugged construction, low leakage, and fast response time make it an ideal protection device for a wide range of applications.
