TVS - Varistors, MOVs, are the critical components of all the common electronic devices in our life. The most familiar device is probably our cellular phone whichrely on this particular type of RC circuit to safeguard itself from sudden and heavily electrical spikes whichare much stronger than normal line signals. Therefore, it is a necessary and important component for the promotion of the modern electrical appliances. The ROV10-331K is a kind of this device, and this paper will discuss its application field and working principle.

The ROV10-331K is a type of varistor. It is a nonlinear, symmetrical semiconductor device that operates around certain specific voltage levels. This product is made according to the ISO9001 standard, in a variety of sizes and shapes. Its working voltage is 175V, and its peak pulsed energy is 15J, which both meet the requirements of UL90 and CSA standards. This kind of component has become widely used in many industries like automotive, consumer, telecom, industrial robotics and medical.

The application field of the ROV10-331K is mainly in the high-voltage electrical circuit. Its main purpose is to provide surge protection for the underlying equipment. As well as the existing protective components such as transient voltage suppressors, it also blocks the high voltage from the power line in the circuit so as to reduce the risk of damage to sensitive components in the circuit. Besides, this kind of device has a wide operating temperature range, which is from -40 to+ 85 Celsius.

Moreover, the ROV10-331K has a high clamping voltage and low residual voltage that allows it to possess the characteristics of wide conduction voltage range, fast response time and high surge current tolerance. By inserting this device inside a circuit, it can offer great protection from significant voltage spikes of up to 700 Volts, which is much higher than the normal operating voltage of the underlying equipmen.

The working principle of the ROV10-331K is quite simple. Basically, this device consists of two electrodes and several metal oxide varistors. During normal operation, there is voltagesignal passing through the two electrodes. When the voltage of the signal reaches the breakdown voltage of the device, the metal oxide varistors, right in between those two electrodes, will conduct this signal until the voltageshe drops below the clampling voltage of the device. When this happens, the electrical current will stop flowing through the varistor, and as a consequence the power line voltage stops going up.

All in all, ROV10-331K is an important component of many electric circuit boards, and this paper explains about its application field and working principle. This device is highly recommended due to its high clamping voltage, fast response time, as well as its wide operating temperature range. It is indeed one the best choice of TVS - Varistors, MOVs, for the electrical industry today.
