TVS-Varistors, MOVs are a type of protection device commonly used in power supplies. They are used to protect against high voltage events, such as transients, bursts of high energy, and lightning strikes. The ROV05H820K is a Varistor manufactured by Signal Path Solutions. This unit, along with other Varistors, is widely used in power supplies, and other applications requiring protection from high voltages.

A Varistor also known as a Voltage Dependent Resistor (VDR) is designed to have a large impedance to low voltages, but when the voltage exceeds a certain voltage level or threshold, the resistance of the Varistor quickly drops, allowing large current to flow, thus protecting the equipment from high voltages. The ROV05H820K is a RoHS compliant Varistor component with a variety of features, such as a fast response, low capacitance, and a long-term stability.

The ROV05H820K Varistor works on the principle of voltage-dependent nonlinear resistance. It is a ceramic disc type, with a fixed current of 8A and a voltage range of 5-820V. The working principle of this Varistor is that when the voltage across the device rises above the rated clamp voltage, the impedance rapidly decreases, allowing large currents to pass, thus protecting the equipment from further damage. This Varistor has a very fast discharge and is capable of withstanding very high surge voltages.

The ROV05H820K Varistor is widely used in a variety of applications, such as in telecommunications equipment, medical equipment, military, and aerospace. It is also used in high-voltage equipment, such as lighting systems, power supplies, and HVAC systems. In addition, it is used as a surge suppressor in all types of communication systems, such as wireless networks, broadband networks, and satellite systems.

The ROV05H820K Varistor has many advantages, such as a high energy absorption capacity, and a long-term stability. It also has a low capacitance and a small package size, which makes it ideal for use in tight spaces. The ROV05H820K Varistor is also temperature and humidity stable, which ensures a reliable operation in a range of environmental conditions.

In conclusion, the ROV05H820K is an ideal Varistor for use in high-voltage applications. Its fast response design and long-term stability make it an excellent choice for protecting sensitive and expensive equipment from damage caused by high voltage events. The ROV05H820K Varistor is also widely used in a variety of applications, ranging from telecommunications and medical equipment to HVAC and lighting systems.
