Overview
METAL OXIDE VARISTOR MOV - 7mm Disc RoHS ü HOW TO SELECT METAL OXIDE VARISTORS • What is the range of ACrms or DC Voltage in the application? • How will the varistor be connected in the circuit? • Calculate the required varistor voltage at 10% to 25% above the system RMS or DC Voltage.
• Calculate the varistor energy rating needed based on energy in transient voltage.
• Calculate the surge current wave form from the surge voltage and surge impedance.
• Check to make sure the withstanding surge current of the varistor is sufficient.
P Type Y Type (most popular) • Check whether the maximum energy and surge life of the varistor is enough.
• Check the relation: Maximum withstanding voltage of the protected device > Maximum clamping voltage of the varistor > The real clamping voltage occurred > Breakdown voltage of the varistor >Operating voltage of the protected device.
