What are the application types of SPD varistors? Let's break it down briefly. The purpose of applying a varistor should be to vary the voltage/current applied to the varistor, depending on the usage. Therefore, the requirements for Barist are also different, and distinguishing these differences is crucial for proper use. Varistors can be divided into two main categories depending on the purpose of their use.

SPD varistor is a resistance device with nonlinear voltammetry characteristics. It is mainly used for voltage clamping when the circuit is subjected to overvoltage, absorbing excess current and protecting sensitive components. The English name is short for "Voltage Dependent Resistor", short for "VDR" or "Varistor". The resistance material of pressure resistor is semiconductor, so it is a kind of semiconductor resistor.

SPD varistor manufacturers think that the varistor has strong electrical characteristics, is a very mature electronic components, can be used in a variety of electronic equipment, to protect the claw, reduce lightning damage, is conducive to improve the stability and use characteristics of the equipment, can be used in lightning protection and automotive electrical and ignition systems

SPD varistor manufacturers see two specific applications for varistors in electronics, one for lightning protection in low-voltage equipment and the other for automotive applications. First, varistors can detect and suppress repeated surge voltages without damage. SPD varistor manufacturers believe that during the summer, low-voltage appliances were damaged by lightning strikes in most parts of south China, which not only caused significant property losses, but also personal injuries.

SPD varistor manufacturers think that varistor is a kind of component at a certain temperature with the increase of voltage and conductance increases sharply, it uses semiconductor material as a resistance, so in nature, it is also a kind of semiconductor resistance.

Thermistor value RC: Generally refers to the actual resistance value of the thermistor when the ambient temperature is 25°C. Actual thermistor value RT: Resistance value measured at a certain ambient temperature.
