V480LU40APX2855 Application Field and Working Principle

Varistors are commonly used in a number of electronics applications, including protection against overvoltage and transient electrical surges. Varistors are multi-layer, bidirectional semiconductor components whose non-linear voltage-current curves provide surge protection from overvoltages. The V480LU40APX2855 is an ultra-thin multifunctional varistor produced by Littelfuse, Inc. The V480LU40APX2855 is designed to provide surge protection to communications equipment, computers, and sensitive industrial applications.

General Structure of V480LU40APX2855

V480LU40APX2855 is a very thin and small nonlinear component that uses multilayer zinc-oxide elements to absorb a surge current. The V480LU40APX2855 is designed with a flexible base substrate and four silver metal layers. It consists of a ceramic plate, a base layer, a top cover, and a solder mask. The four silver-plated metal layers are cathodes, anodes, and chain cathodes. The anode and cathode form two terminal surfaces, and the other two cathode layers form two more, making the V480LU40APX2855 a four-terminal device.

Working Principles of V480LU40APX2855

The working principle of V480LU40APX2855 is based on the principle of a spark gap. A spark gap is a device that will break down when the voltage across it exceeds a certain value. The working principle of the V480LU40APX2855 is based on the same principle. When a surge voltage is applied across the V480LU40APX2855, it starts conducting current when the voltage reaches a certain, predetermined value. The V480LU40APX2855 will then continue conducting current until the voltage drops below some predetermined limit. The V480LU40APX2855 is designed to limit the surge current through it, thus protecting the circuit from possible damage.
