Firstly, varistor use special materials to manufacture varistors during the production process. These materials typically include ceramic powders, metal oxides, and additives. These materials undergo electrical changes under the action of electric or thermal fields and exhibit nonlinear volt ampere characteristics. The unique material formula and preparation process of varistors enable them to have the characteristic of variable resistance value.

Secondly, the nonlinear volt ampere characteristics of varistors can be divided into two types, namely VDR varistors (Voltage Dependent Resistors) and MOV varistors (Metal Oxide Varistor). The resistance value of VDR varistors undergoes linear or nonlinear changes with voltage, serving as a voltage regulator for protection. MOV resistors are mainly used for high voltage protection, which can quickly respond to situations of excessive voltage and protect electronic devices from damage.
The special feature of varistors is that they are based on high impedance under normal working conditions and will not have a significant impact on the circuit. However, when the circuit is subjected to excessive voltage shocks, varistors will quickly become low impedance through their nonlinear characteristics, absorb electrical energy, and convert it into thermal energy for dissipation. This nonlinear response characteristic makes varistors widely used in electronic products for overvoltage protection and reliability enhancement.
It is worth noting that varistors also have a certain service life. After being subjected to overvoltage impact, the nonlinear volt ampere characteristics of varistors will gradually deteriorate, and their protective ability will be weakened. Therefore, in high voltage or overvoltage environments, varistors should be selected reasonably and tested and replaced regularly.
In summary, as a special type of resistance device, varistors have unique nonlinear volt ampere characteristics, which play a role in circuit protection and signal regulation. Varistor manufacturers produce VDR varistors and MOV varistors suitable for different scenarios by selecting special materials and preparation processes. The special feature of these resistor devices is that they have high impedance under normal operating voltage but can quickly become low impedance under overvoltage impact and absorb electrical energy for protection. In practical applications, attention should be paid to the service life of varistors to ensure their continuous and effective functioning.
