Varistors Circuit Digest Ultra surge, high temperature varistors for industrial applications vishay intertechnology released a new series of vdr metal oxide varistors (mov) certified for operation up to 125 °c in…. In this project, we go over how to build a simple varistor circuit so that it can protect sensitive electronics from excess voltage.
Circuit Digest Photo Varistors are devices which have a high electrical resistance for low applied voltages, which decreases as the voltage is raised. when placed in parallel with a piece of electrical equipment, varistors thus provide a circuit breaker effect at high voltages. A simple equivalent circuit representing a metal oxide varistor as a capacitance in parallel with a voltage dependent resistor is shown in the equivalent circuit model drawing. Varistors represent a critical component in the protection of electronic circuits against overvoltage events. their unique non linear resistance properties enable them to effectively safeguard sensitive components from transient voltage spikes that could otherwise cause catastrophic failure. It explains how varistors work by changing their resistance when the voltage gets too high. you will learn about how they are built, the different types available, and where they are commonly used.
