A varistor is an abbreviation for a voltage sensitive resistor and is a non-linear resistance element. The resistance of the varistor is related to the magnitude of the voltage applied across the two ends. When the voltage applied to the varistor is within its nominal value, the resistance of the re

The varistor is represented by the letter “MY”. If J is used for household use, the following letters W, G, P, L, H, Z, B, C, N, and K are used for voltage regulation, overvoltage protection, and high frequency. Circuit, lightning protection, arc extinguishing, noise cancellation, compensation, dega

1.Lightning protectionLightning strikes can cause atmospheric overvoltages. Most of them are inductive overvoltages. The overvoltage generated by the lightning strike on the transmission line is called the direct lightning overvoltage, and its voltage value is particularly high, which is extremely h

1. The working principle of varistor connected in parallel with the circuitThe varistor is equivalent to a variable resistor. It is connected in parallel with the circuit. When the circuit is in normal use, the varistor has a high impedance, and the leakage current is small. It can be regarded as an

1. Principle of varistorA varistor means "the resistance value varies with voltage within a certain current-voltage range" or a resistor whose resistance value is voltage-sensitive. The corresponding English name is “VoltageDependentResistor” and is abbreviated as “VDR”. As the voltage applied to it

A varistor is a kind of resistance device with nonlinear volt-ampere characteristics. It is mainly used for voltage clamping when the circuit is subjected to overvoltage, and absorbs excess current to protect sensitive devices. The resistor material of the varistor is a semiconductor. It is a voltag

1. The working principle of varistorWhen the varistor is in operation, each varistor unit is subjected to surge energy, and the varistor units are substantially evenly distributed throughout the resistor body, that is, the entire resistor body bears energy, unlike The nano-polar regulator tube is ju

A varistor is a resistive device with nonlinear volt-ampere characteristics. It is mainly used to clamp the voltage when the circuit is under overvoltage, and to absorb excess current to protect sensitive devices. Nowadays, the varistor is widely used, and its main material is composed of a divalent

In order to meet the space size requirements of equipment miniaturization and meet the needs of functional upgrades, power supply, battery management and special system functions are required. More and more electronic components requiring varistor protection in highly integrated circuits are require

Varistors are often used in the lightning protection of instrument equipment power supply. Anti-surge design In these applications, varistor is usually used together with gas discharge tubes, fuses, thermistors and other devices to better play together. effect. The varistor lightning protection has
