Metal zinc oxide varistor Lightning Arrester ZnO MOV Blocks customized

Product Specification

   Lightning Arrester ZnO MOV Blocks is the core of the arrester/lightning arrester, whose main component is Zinc Oxide and with as small quantity of metal oxide,fluoride oxide,manganous carbonate, antimony oxide and other gleam of additive and made with high temperature.
 

Features 

Zinc oxide resistors have the following characteristics:

• Have high energy ability. Zinc oxide is a semiconductor material that has good electrical conductivity and can therefore have a high resistance value to limit the flow of current.
• Excellent stability. Stability refers to the ability of a resistor value to remain constant under certain conditions. High-energy zinc oxide resistors usually have a small temperature coefficient and a small resistance drift, which means that under different temperature and voltage conditions, their resistance values change less, which can keep the stable operation of the circuit.
• Large flow capacity, low limiting voltage, fast response speed, non-polarity, low temperature coefficient, etc.

Application

Zinc oxide varistor (MOV blocks) is an overvoltage protection device, that is mainly used in electronic equipment, and has the effect of protecting the circuit from voltage peak and transient overvoltage. The following are the specific applications of zinc oxide varistor:

1. In the automotive electronics industry, zinc oxide varistors can protect the entire vehicle circuit from instantaneous high-voltage damage by absorbing electrical energy.

2. In the field of communication, zinc oxide varistor plays an important role, it can play a role in the transmission of line circuits, and can eliminate the noise caused by transmission, and ensure the quality of communication.

3. In addition, zinc oxide varistors are also widely used in chemical, electronic, electrical, instrumentation, and mechanical industries, as they can withstand high temperatures, humidity, and corrosive environmental impacts.

4. Zinc oxide varistors can also be used in inductors, temperature sensors, and microwave circuits.
In addition to the above-mentioned applications, zinc oxide resistors can also be used for functions such as current limiting, voltage divider, and resistance regulation in electronic devices. For example, in DC power supplies, zinc oxide resistors can be used to limit the magnitude of the current and protect the circuit and equipment from excessive current damage. In a voltage-dividing circuit, it can be used to reduce the magnitude of the voltage to meet specific circuit needs. In addition, by changing the resistance value of the resistor sheet, the stability of the circuit can also be adjusted.
