Protection function of varistor: 1. Surge suppression type: refers to a varistor used to suppress transient overvoltages such as lightning overvoltage and operating overvoltage. The occurrence of transient overvoltage is random, non-periodic, peak of current and voltage. It may be very big. Most var

If the circuit is not the same, the input voltage and current will be different. Excessive current can destroy important devices. The varistor is a voltage limiting protection device in a special voltage range. It is a key point, adding a persistently high varistor voltage value, and not presenting

Is the diameter of the varistor related to the flow rate? The larger the diameter of the varistor, the higher the flow rate. In general, pressure sensitive resistance manufacturers are based on guidelines for pressure relief. That is to say, according to the 2/5 wave of pressure sensitive criterion,

When the voltage at both ends is within the nominal rating of 1, its resistance value is almost infinite, and it is in a high resistance state. The leakage current varistor exceeds its action voltage to produce the current to clamp the overvoltage and eventually converts the electric energy into the

When the voltage at the two ends of the varistor is lower than the nominal rated voltage, the resistance value of the varistor is close to infinity, and there is hardly any internal current flowing through it. When the voltage at both ends of the varistor is slightly higher than the nominal voltage,

Varistor is an electronic component which can prevent high voltage and protect the circuit board from high impact. The resistance material of varistor is semiconductor, so it is also a kind of semiconductor resistor. The Zinc Oxide varistor is commonly used now. There is a key parameter in the varis

So, does the diameter of the varistor relate to the flux? The larger the diameter of the varistor, the higher the flux. In general, the voltage sensitivity of the manufacturer of varistor dredging is based on the criteria. That is to say, the variable-rate index of the variable-voltage is not higher
