82535300 Circuit Protection

A varistor is a type of voltage-dependent resistor designed to protect sensitive electronic circuits from excessive transients and overvoltage conditions. The 82535300 varistor, specifically, is a chip varistor that utilizes a metal oxide, or MOV, as its base material, allowing it to be highly efficient at sensory charge protection.

Application Field

The 82535300 varistor is mainly utilized in telecommunications, consumer electronics, and computer systems, notably for overvoltage and ESD protection. This type of varistor is ideal for use in a medium-voltage range, providing efficient protection without degrading important electrical signals including RF, USB, and ethernet.

Below is a list of applications that may benefit from the use of the 82535300 chip varistor:

• Industrial Control System
• Automotive Applications
• Cellular Phone and PDA Applications
• Computer and Peripherials
• Hard Disk Drives and Floppy Drives
• Networking / Communication
• Wireless LAN / Bluethooth

Working Principle

The 82535300 varistor is designed to provide effective protection against transients and overvoltage conditions. It is essentially an electronic switch that clips or absorbs voltage spikes before they are transferred on to damaging sensitive electronic components. When the voltage across the MOV increases above its rated voltage, known as the breakover voltage, it will decrease its resistance, thereby discharging the electrical surge.

In normal operation, the chip varistor has high resistance and protects the sensitive electronics or equipment it is connected to. When an overvoltage transient occurs, the resistance of the MOV decreases providing an alternative path for the surge and thus protecting the equipment. As the surge ends the resistance of the MOV increases to its original value.

The 82535300 chip varistor is highly efficient and reliable in operation due to its unique construction. It has temperature and frequency characteristics that are superior to other types of MOVs and its excellent charge handling capabilities provide reliable ESD protection.

Conclusion

The 82535300 chip varistor is an extremely reliable way of protecting electronic equipment from overvoltage and transient surges. It is highly effective in protecting sensitive components and can be used in many applications. It also has the added benefit of being temperature and frequency efficient making it a great choice for wireless LAN and bluetooth applications.
