What is a metal oxide varistor? The Metal Oxide Varistor or MOV is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. The Metal Oxide Varistor is designed to ...

KOA Speer Electronics has brought out a multilayer type metal oxide varistor that handles a surge current of up to 6,000A. The multilayer construction of the NV73S can absorb a large surge despite its ...

Varistor ceramics, predominantly based on SnO₂, are engineered to exhibit a highly non‐ohmic current–voltage relationship that is critical in safeguarding electrical circuits from transient voltage ...

Varistors, also called metal-oxide varistors (MOVs), are used to protect sensitive circuits from a variety of overvoltage conditions. Essentially, these voltage-dependent, nonlinear devices have ...

I want to share a experience related to some of our project. We have a 3 phase AC supply to our board, which will be rectified and given to power supply section ( buck and fly back converter stage).

To see this article in PDF format, please click here. New regulations concerning surge protection are forcing engineers to look for solutions that allow such protection to be incorporated at minimal ...

ZnO varistor ceramics were synthesised by cold sintering/spark plasma sintering and post-annealing treatment. Intriguingly, the ZnO varistor ceramics present ultrahigh potential gradient, high ...
