TVS - Varistors, MOVs are electrical components which are mostly used in order to protect electrical systems from overvoltages. The ROV05H820K-S-2 Varistor is one such product, and it is widely used in applications such as telecom/data lines, automotive equipment, AC/DC line connection, and in industrial and home electronic equipment.

The ROV05H820K-S-2 Varistor is made using metal oxide film materials which are coated with zinc oxide and encased in a plastic housing. This housing prevents accidental contact with the metal oxide material, as it is very hazardous if touched. The Varistor is designed to be used in AC mains connections and provides high levels of protection against transients generated from lightning strikes, switching surges, and ESD or electrostatic discharges.

The working principle of the ROV05H820K-S-2 Varistor is based on its Varistor voltage which is also known as the nonlinear voltage-current characteristic. When an overvoltage is applied to the Varistor, its Varistor voltage decreases until the threshold voltage, at which point the Varistor conducts and provides protection. When the overvoltage is removed, the Varistor voltage increases back to its original value. This allows the Varistor to provide strong protection without damaging the components it is protecting.

The ROV05H820K-S-2 Varistor is capable of handling high surge current levels, up to 3.5kA, and can react to transients at the rate of 53V/µs. It also offers a high level ofthermal and environmental protection, making it suitable for use in a wide variety of industrial, telecom, and automotive applications. The Varistor provides protection against a range of overvoltages, from 600V rms up to 800V peak and has a long life expectancy of up to 10 years.

The ROV05H820K-S-2 Varistor can be used in a variety of applications. One of the most common applications is power line transient protection, where the Varistor is used to protect sensitive electronic components from damage due to transients. It can also be used in telecom/data line protection applications, as it is able to provide protection against both ESD and surge voltages. In automotive applications, it can be used to protect automotive ECUs, audio systems, and electric windows from electro-magnetic interference (EMI).

The ROV05H820K-S-2 Varistor has many benefits and can provide reliable protection for a wide variety of industrial, telecom, and automotive applications. With its high surge handling capability, thermal and environmental protection, and long life expectancy, the ROV05H820K-S-2 Varistor is an ideal choice for protecting sensitive electrical components from overvoltages.
