Varistors, also known as voltage-dependent resistors (VDRs) or simply a Voltage Dependent Resistor (VDR), are non-linear, two-terminal components that are used for protecting electronic circuits from voltage transients and surges. MOVs (Metal Oxide Varistors), are probably the most widely used type of Varistor. These components are usually made of a metal oxide material and serve to protect circuits against harmful voltage transients. MOVs or Varistors offer protection by limiting the maximum rated voltage transient and absorbing the energy of incoming electrical surges, enabling the circuit to survive and continue operating after the transient has been absorbed and dissipated.

The 82550060 Varistor is one such product and is one of the most popular Varistors on the market today. This product is an ultra-small metal oxide Varistor with a high rated current, high withstand voltage and fast response time. Its ultra-small size makes it perfect for high- density circuit designs, while its low creepage and coating resistance increase safety and reliability against the risk of electric shock. Moreover, the 82550060 Varistor has a superior sensitivity to transient voltage, providing excellent surge protection for sensitive electronic equipment.

82550060 Varistors are designed to protect against high-voltage transients or spikes and are commonly used in automotive, power, communication, industrial control, portable electronics, as well as other higher current, higher voltage applications. Typical applications include overvoltage and overcurrent protection in switch mode power supplies, home appliances, communication equipment, ground fault interrupt and lightning surge protection and other protection requirements.

The 82550060 Varistor is designed with a Zinc Oxide Varistor (ZOV) ceramic core, a metal coating and a polyolefin coating. The metal coating consists of an abrasion-resistant and corrosion-resistant layer that improves environmental performance. The polyolefin coating is used to ensure a reliable contact between the Varistor and the PCB and increases the Varistors\' thermal and electrical properties. The Varistor’s ZOV ceramic core helps by providing excellent response to overvoltage and overcurrent events, as well as surge protection characteristics. This helps to ensure a reliable connection between the Varistor and the PCB, allowing energy to be released quickly during voltage and current surges.

The working principle of a 82550060 Varistor is simple. The Varistor acts as a voltage-dependent resistor between two terminals. When the voltage reaches its rated voltage, the Varistor is activated and a current passes through the Varistor. This current is then diverted to the other terminal, or absorbed and dissipated, depending on the applications’ requirements. The diverted current is then dissipated as heat or absorbed by a grounding source depending on the application. The Varistor will then reset itself and be ready for another transient.

82550060 Varistors are also designed with an inbuilt overvoltage clamp, which acts to limit the destructive voltage spike from propagating within the system. The overvoltage clamp feature of a Varistor, coupled with its voltage-dependent resistance, helps protect sensitive electronic components by limiting the detrimental voltage transients that occur during inrush and electrical surge events. The 82550060 Varistor is also able to dissipate the heat generated from these events, helping to further protect sensitive equipment.

In conclusion, 82550060 Varistors are an important component of many electronics systems. They offer reliable protection against voltage transients and surges, while ensuring the system continues to operate reliably following the transient event. Varistors are widely used in automotive, power, communication, industrial control, portable electronics, and other higher current, higher voltage applications providing reliable and efficient surge protection.
