Varistors, also known as voltage-dependent resistors (VDRs), are commonly used over-voltage protection components. By absorbing the excess energy of a real-time pulse, the varistor will protect connected components from any potential damage. ROV20H102K-2 is an example of an upcoming varistor in the TVS Varistors, MOVs category. This document will take a look at the application field and the working principle of the ROV20H102K-2.

The ROV20H102K-2 is a new type of varistor that has an additional 3rd contact pin for improved current flow capability. Thisvaristor works well in environments with a minimum operating temperature of -55°C and a maximum temperature of 115°C. The ROV20H102K-2 has an AC and DC operating voltage range of 220V to 1000.V, providing a wide operating range for a variety of applications.

The ROV20H102K-2 is most desirable for use in consumer electronics, automotive, and industrial applications. This device is known for providing excellent protection from transients such as AC inrush surge, ESD, amplifier couplers, and contact spikes, as well as leakage current protection. ROV20H102K-2 also has excellent fire and overvoltage resistant qualities and can withstand an electric field of 10KV/mm.

The working principle of the ROV20H102K-2 is quite simple. This component absorbs the excess energy of a real-time pulse, thus protecting the connected components from any potential damage. The conductive path of the varistor is normally open, and the voltage across all the terminals of the varistor will remain low while no voltage is present. However, when the voltage across the terminals exceeds the momentary threshold of the varistor, it will abruptly reduce the resistance of its path thus allowing current to flow. This surge of current will then be absorbed by the ROV20H102K-2, thus reducing the amount of voltage present and protecting against any potential damage.

In conclusion, the ROV20H102K-2 is an excellent varistor for a variety of applications. It is suitable for use in consumer electronics, automotive and industrial applications and provides excellent protection from transients. Moreover, this device is capable of withstanding an electric field of 10KV/mm and has an AC and DC operating voltage range of 220V to 1000V. Finally, its working principle is straightforward with the varistor path normally open and when the voltage across its terminals exceeds its threshold, the resistance reduces and current will flow.
