What is a self-restoring fuse Self-restoring fuse is a kind of overcurrent electronic protection element, using high molecular organic polymer under the conditions of high pressure, high temperature, vulcanization reaction, adding conductive particle material, through a special process. The traditional fuse overcurrent protection can only be protected once and needs to be replaced when it is burned out, while the self-restoring fuse has the dual function of overcurrent overheat protection and automatic recovery.

The difference between DC fuses and AC fuses. With the increasing demand for DC fuses in industries, rail transit, and new energy vehicles, how to correctly select DC fuses for effective protection is a problem that users and manufacturers should take seriously. When selecting DC fuses, it is not possible to simply copy the electrical specifications and structural dimensions of AC fuses, as there are many different technical specifications and design concepts between the two, A comprehensive consideration of whether to safely and reliably cut off fault currents and prevent accidents.

Varistor is a special resistance device, which can play a very important role in the circuit. Its main feature is that it has nonlinear resistance characteristics, that is, its resistance value is high when the voltage is low, and its resistance value will drop rapidly when the voltage is high, which makes Varistor have a good overvoltage protection function in the circuit.

Correct connection of Varistor Varistor is a kind of component widely used in electronic equipment. It has the characteristics of high sensitivity and fast response. In order to ensure the stability and normal operation of Varistor, correct connection is very important. This paper will introduce the correct connection of Varistor and its application in electronic circuit in detail.

The varistor is often used in parallel with the protected device or device. Under normal conditions, the DC or AC voltage at both ends of the varistor should be lower than the nominal voltage. Even in the worst case of power fluctuation, it should not be higher than the maximum continuous working voltage selected in the rated value. The nominal voltage value corresponding to the maximum continuous working voltage value is the selected value.

A varistor, also known as a particle piezoresistive resistor, is an electronic component whose resistor has nonlinear resistance characteristics. Its application involves many fields, including circuit protection, overvoltage protection and generation of radio waves. In this article, we will delve into how varistors work, introducing you to their characteristics and applications.
