Fixed inductors are passive two-terminal electrical components with electromagnetic coils around a core. A fixed inductor, such as the FSLU2520-18NKP2, is usually used to either store electromagnetic energy in a circuit or prevent the flow of AC by creating a magnetic field. This article will discuss the application field and working principles of the FSLU2520-18NKP2.

Application

The FSLU2520-18NKP2 spans a wide range of applications, from industrial to consumer electronics. In AC circuits, these fixed inductors are commonly used as output inductors in power supplies and DC-to-DC converters. They are also used in cell phones, laptops, computers, TVs, and other personal electronics to reduce electromagnetic interference. Likewise, FSLU2520-18NKP2 inductors can filter out high frequencies, which makes them great for amplifiers and dust filters.

In addition, FSLU2520-18NKP2 inductors can be used in resonance circuits, or in combination with other components to form oscillators for communicating with radio waves. Due to their low power requirements, these fixed inductors can be used in low-power applications such as switched-mode power supplies or small battery systems.

Working Principle

The FSLU2520-18NKP2 fixed inductor uses a combination of a wound inductor core and a ferrite material to store magnetic energy. The ferrite material, which is usually a ceramic, and the winding on the core create an inductive reactance that induces a voltage when current passes through it. When an electric current flows through the inductor, it creates a magnetic field that stores energy and thus creates a current loop. This current loop will be in effect as long as the current remains steady.

When current flows through the FSLU2520-18NKP2 inductor, the magnetic field flux also circulates inside the core. The field flux circulates in both clockwise and counterclockwise directions and creates its own current dependent on its own magnetic field. This current opposes the current going through the inductor and is known as inductor reactance.

The FSLU2520-18NKP2 inductor\'s reactance is a measure of the inductor\'s opposition to current. The inductor\'s reactance is proportional to the frequency of the applied current, so a higher frequency will create a higher resistance. The amount of inductor reactance is determined by the inductance of the core and the number of winding turns.

To obtain a higher inductance, the FSLU2520-18NKP2 inductor employs a mutually insulated ferrite core. This means that if a higher current is applied, the core produces more magnetic flux. With two windings, the ferrite core is able to create a higher inductance and create a stronger inductive reactance, which is desirable in certain applications.

Conclusion

The FSLU2520-18NKP2 fixed inductor is an excellent choice for a variety of uses, from industrial to consumer electronics. Its wide range of applications include serving as output inductors in power supplies and DC-to-DC converters, filtering high frequencies, and forming oscillators for communicating with radio waves. In addition, these inductors use a ferrite core to store magnetic energy and mutually insulated to produce more magnetic flux and higher inductance.
