ROV10H621K-S-2 Varistor is a voltage sensitive device designed to provide protection for circuits in which higher voltage would lead to catastrophic failures. The purpose of a ROV10H621K-S-2 varistor is to provide an alternate path for high voltage or current generated in faulty circuits. Varistors are passive devices with a voltage dependent resistance – when the applied voltage exceeds a certain level, the resistance decreases rapidly. By diverting the excess current away from vulnerable components, varistors can significantly reduce the likelihood of an overvoltage event.

The ROV10H621K-S-2 Varistor is a metal oxide varistor (MOV), a popular type of voltage surge and spike protection component. A MOV contains a ceramic material formed from zinc oxide and other metal oxides that act as the voltage dependent resistor. When a voltage surge is sensed, the MOV will immediately decrease its resistance, thereby providing an alternate path for the surge and reducing the likelihood of irreversible damage. The ROV10H621K-S-2 has a 10kA peak current rating, a maximum voltage of 6.2V, and a clamping voltage of 23V.

ROV10H621K-S-2 Varistors are commonly used in a wide range of applications, such as in power supply overvoltage protection circuits, in protecting communication lines from voltage spikes, in protection circuits for consumer electronics, or as an ESD protection device in sensitive electronics. Furthermore, the ROV10H621K-S-2 Varistor can be used in applications where noise and transients have to be suppressed, for example in automotive, domestic, and industrial environments.

The working principle of a ROV10H621K-S-2 Varistor is relatively simple. When a voltage is applied to the device, the metal oxide layers of the component create a voltage dependent resistance. The resistance is high when the applied voltage is low, but it rapidly decreases when the voltage exceeds the breakdown threshold of the device. This reduces the likelihood of circuit failure and component damage occurring as a result of overvoltage events.

The ROV10H621K-S-2 Varistor is a reliable and effective surge protection device that can protect vulnerable circuits from overvoltage damage. With its wide range of applications, it is the ideal choice for a range of power supply, communication line, and ESD protection needs.
