Varistor - Engineering Center

• Differences between silicon carbide (SiC) varistors and MOV varistors are: ‒ MOV’s Leakage current is much lower. ‒ MOV’s clamp transients much faster. How Does It Work? • As the voltage between the terminals of the varistor increases, the resistance of

What is a Varistor? Definition, construction, operation, …

A standard silicon carbide is different from the metal oxide varistor in the way that a MOV exhibits less leakage current and its operational speed is faster. Operation and Characteristic of Varistor Before proceeding towards its operation, let us first understand the relationship between voltage and resistance of varistors.

Silicon Carbide SiC Material Properties - Accuratus

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
