Fixed inductors are a type of passive electrical component that store energy by creating a magnetic field when electric current flows through it. LQW15AN4N0B80D is one kind of fixed inductor. It is specially designed for high frequency application and is able to provide a high current, low-inductance, and low-resistance. This article will discuss the application field and working principle of LQW15AN4N0B80D fixed inductor.

Application field

LQW15AN4N0B80D fixed inductors find its application where frequencies go up to 5GHz. They can be used as a noise eliminator, RF blocking, and EMI suppression in the power lines. These fixed inductors are usually applied to decoupling, DC/DC converters, and filtering applications that require high current handling capabilities.

The LQW15AN4N0B80D fixed inductor has a wide range of applications due to its high current and wide frequency range. It is used in installations that involve disconnection and reconnection, such as high speed signal transmission lines and for DC/DC converters, buck-boost controllers, resolver-type AC-DC converters, RF amplifiers, LCD display drivers, automotive relays, motor control applications, and power supplies. This type of fixed inductor also finds application in wireless mobile communication systems, LAN server, home appliance, and audio amplifiers.

Working Principle

A fixed inductor is composed of a coil of insulated wire, most often copper, wrapped around a ferrite or powdered-iron core. When current flows through an inductor, a magnetic field is developed around the coil. The inductor then acts as an opposition to the initial current and limits the rate of current flow. This opposition is known as inductance. The more turns of wire are wound around the inductor core, the higher the inductance.

When the current changes with respect to time, the electromagnetic field changes accordingly. This electromagnetic field induces an EMF (electromotive force) in the inductor, which, in turn, counters the change that causes it. This is known as reactance and plays a major role in working of the inductor.

In the case of LQW15AN4N0B80D fixed inductor, the interwinding capacitance and self-resonance are minimized, resulting in a high frequency use that can go up to 5GHz. Moreover, due to its low resistance, it exhibits highly stable inductance with little variation in current levels. Furthermore, its wide temperature range, tight tolerance, and low profile package make it suitable for a variety of applications.
