METAL OXIDE VARISTOR MOV - 5mm 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. 5 f JVR VARSITOR Part Maximum Varistor Maximum Withstanding Rated Energy UL CSA VDE Number Allowable Voltage Voltage Clamping [email protected] Voltage Surge Current Wattage 10/1000 ms ACrms DC Tolerance V@ 5A 1Time 2 Times (V) (V) (V) Range (V) JVR05N180M65£rr 11 14 18 + 20% 40l 1) JVR05N220L 65£rr 14 18 22 + 15% l 48 JVR05N270K65£rr 17 22 27 l 60 JVR05N330K65£rr 20 26 33 l 73 JVR05N390K65£rr 25 31 39 l 86 JVR05N470K65£rr 30 38 47 l 104 JVR05N560K65£rr 35 45 56 l 123 JVR05N680K65£rr 40 56 68 l 150 JVR05N820K65£rr 50 65 82 145 JVR05N101K65£rr 60 85 100 175 JVR05N121K65£rr 75 1...
