Varistors, more commonly known as Transient Voltage Suppressors (TVS) are active components used to protect other electronic components from overvoltage transients. The ROV10H301K-2 is a 200V Metal-Oxide Varistor (MOV) designed to protect electronic components from voltage transients in a wide variety of applications.

MOVs are non-linear devices that have anode and cathode electrodes connected to a nonlinear semi-conductor layer. When the voltage level applied to one of the electrodes exceeds the breakdown voltage of the device, current begins to flowing through the device, resulting in a sudden drop in voltage at the electrodes. These devices have low resistance when they are not exposed to to voltage transients, thus preventing any current flow through the device until the voltage level exceeds its breakdown voltage.

The ROV10H301K-2 is a 200V MOV designed to protect high-voltage systems such as telecom, medical, automotive, and industrial equipment from voltage transients. It has a pulse rating of 4500A (8/20 microsecond), and a peak power rating of 30J. It is UL recognized, and offers superior surge handling capability in both single- and three-pulse conditions.

The working principle of the ROV10H301K-2 is to offer an alternate path for current when the system is exposed to a voltage transient. The device can conduct a high level of current for a short time, during which the transient noise is dissipated. This protects the other components of the system from damage due to the transient. The device also reduces the noise in the system, making it less susceptible to interference from external sources.

The ROV10H301K-2 is designed for use in a wide variety of applications, including telecom and industrial equipment, medical devices, automotive systems, house appliances, and consumer electronics. It is also suitable for protection against lightening-related transients. With its wide applicability, superior surge handling capability, and low resistance during normal operation, the ROV10H301K-2 is a ideal choice for protecting high voltage systems from voltage transients.
