How to Select MOV – Explained with a Practical Design
Mar 11, 2024 · MOVs or metal oxide varistors are devices designed for controlling mains switch ON surges in electrical and electronic circuits. Selecting an MOV for a particular electronic circuit might require some consideration and calculation, I have explained the procedures here.
is it possible? MOV or varistor instead of NTC-5d 9? - Page 1
Mar 17, 2016 · MOV (or "varistor") is a resistor with voltage dependence. The higher the voltage, the less the resistance. Used only for surge/spike voltage protection. At normal conditions and operating voltage, almost no or negligible current flows.
