TVS - Varistors, MOVs: Varistor V481DA40 Application Field and Working Principle
V481DA40 varistors are cylindrical components with two metal tabs at the top. They feature a high temperature rating and a relatively low operating voltage, making them well-suited for a variety of industrial and electronic applications.
The varistor\'s working principle is straightforward. It is essentially a two-terminal device, with one terminal connected to earth. When a voltage is applied between the two terminals, the junction increasingly resists and charges collect at the junction. This results in a ‘crowbar’ action when the voltage exceeds the rated voltage, clamping the voltage to the specified value. This helps protect any sensitive devices connected to that circuit.
The V481DA40 is a type of varistor commonly utilized in telecommunication and computing equipment, because it can readily provide lightning protection and ESD protection. It can also be used in switches, amplifiers, machines, cars and lighting fixtures. The devices feature a movable element, enabling them to effectively absorb and control static electricity or spatial voltage.
The V481DA40 varistors feature a wide operating temperature range, making them well-suited for many different applications. The device also features low leakage current, making it ideal for use in computers and other sensitive electronic systems. The device is also capable of withstanding high voltages and long-term operation under harsh conditions.
The V481DA40 is also designed with high insulation resistance and a strong resistance-to-temperature coefficient. This enables the component to maintain its rating against the environmental changes and also maintain its rating during long term operation.
These varistors are relatively inexpensive and easy to install, making them popular among electrical and computer engineers for many different applications. In addition to providing long-term protection against high voltages, the device also features a relatively low failure rate when properly used.
