Varistors are commonly used in lightning protection and power surges at the power inlet of equipment. The main parameters of the varistor are: varistor voltage, current capacity, junction capacitance, response time and so on. What is the main role of the commonly used lightning protection varistor?

Lightning varistor is basically a necessary electronic component for each of us. The lightning varistor is a resistor in which the resistance value changes with the voltage in a certain current and voltage range, or the resistance value is sensitive to the voltage. What should we pay attention to in

2 The operating voltage of the lightning varistor (the voltage applied continuously across the lightning varistor) must not exceed the "continuous operating voltage" value listed in the technical parameters table of the lightning varistor.3 Lightning varistor operating temperature should be within t

Lightning varistors are basic electronic components that we all must have. Lightning varistors mean that the resistance value changes with voltage in a certain range of current and voltage, or that the resistance value is sensitive to voltage. Resistor. In the use of lightning varistors we should pa
