Fixed Inductors consist of inductors with a fixed inductance, meant to restrict current in a circuit and save it from overload. The LQW15AN4N8B80D Fixed Inductor falls into this category of inductors, and their application field and working principles are explained here.

Application Field

The LQW15AN4N8B80D Fixed Inductor finds uses in many different applications. Its construction is particularly well-suited for narrow-band filter, impedance transformer, power switching, audio output, and power line filter applications. It can also be used in radio receivers and transmitters, solenoid control, RF filters, and even as a noise filter.

Working Principle and Design

The LQW15AN4N8B80D Fixed Inductor works on the principle of Faraday’s law of induction. It is a two-terminal device that consists of a coil of wire with an internal core. The core is composed of a magnetic material, such as ferrite or iron powder, that is used to increase the inductance of the coil. The length and turns of the coil determine the inductance of the inductor, which acts as an electromagnetic barrier.

When a current flows through the inductor, it creates an electromagnetic flux around it. This flux interacts with the internal core, creating a feedback loop that restricts the maximum current that flows through the inductor. The result of this feedback loop is that the inductor behaves like an electromagnetic resistance to all incoming currents, thus protecting the circuit from overload.

Mechanical Structure

The LQW15AN4N8B80D Fixed Inductor is composed of a coil of wire wound around a circumference of an inner core. The diameter of the core is 8.0 millimeters, while the thickness is only 4.0 millimeters. The diameter of the coil is 5.5 millimeters. The entire structure is housed in a robust plastic casing, while its electrical connections are soldered onto both ends of the inductor.

Conclusion

The LQW15AN4N8B80D Fixed Inductor is a two-terminal device made to limit current and protect the circuit from overloads. It works on the principle of Faraday’s law of induction, and its mechanical construction is composed of a coil of wire wound around a core of ferrite or iron powder. In many different applications, such as narrow-band filter, radio receivers, and power line filter applications, the LQW15AN4N8B80D Fixed Inductor is a popular inductor choice.
