ESD interferes with the work of electronic products, and the damage of it causing to electronic products has attracted people’s attention. So it is necessary to prevent ESD so as to protect electronic circuits. What is ESD and what hazards it may cause? How to deal with it?
With the development of miniaturization and multi-function of electronic products, electronic products have higher and higher requirements for circuits. ESD interferes with the work of electronic products, and the damage of it causing to electronic products has attracted people’s attention. So it is necessary to prevent ESD so as to protect electronic circuits. What is ESD and what hazards it may cause? How to deal with it?
1. What is ESD?
In the field of electronics, ESD (Electro-Static discharge) means electrostatic discharge, which refers to the static electricity released when two objects are in contact.
2. How does ESD come about?
ESD occurs when two different materials are in contact or rubbed. The negative charge is attracted by the positive charge. The current discharge voltage generated by the attraction can be as high as tens of thousands of volts. The heat generated by electrostatic discharge is very high, and the human body will not feel it. When a charge is released onto an electronic device, the large heat from the charge can melt tiny parts of the electronic device, causing the device to malfunction.
3. The hazard of ESD
1. Electrostatic discharge will break down the device and damage the device, thereby reducing the reliability of the device.
2. Electrostatic discharge will radiate radio waves with frequency, causing electronic interference and affecting the normal operation of the device.
3. Sparks will occur when static electricity is discharged, which is easy to cause fire and explosion.
4. How to solve ESD?
As a surge protection device, the varistor can be used in ESD protection, because the varistor has the advantages of nonlinear characteristics, large flux, strong surge resistance, and fast response speed, providing a discharge channel for electrostatic discharge, eliminating sparks, inhibiting the intrusion of dangerous static electricity into electronic equipment. The varistor acts as a suppressor to protect the equipment and circuits from electrostatic discharge.
ESD is an important cause of malfunction or damage of electronic products. With the development of technology and the improvement of product complexity, everyone also pays attention to the harm of ESD to electronic products. As a surge protection device, varistor has its own advantages. It is used in ESD protection occasions and plays an important role in ESD protection.
Select a reliable manufacturer when purchasing varistor can avoid a lot of unnecessary trouble. JYH HSU(JEC) Electronics Ltd factories are ISO 9000 and ISO 14000 certified. If you’re looking for electronic components, welcome to contact us.
