Fixed Inductors

Fixed inductors, commonly denoted as L in electrical schematics, are an electrical component used most often to store energy in the form of an electrical field. Usually, it is in the form of a short-circuited coil wound on a ferrite core, metal core or an air core. The value of the inductor is determined by the number of coils, the core material and the size of the coil.

L0201R82AHSTR Inductor

The L0201R82AHSTR Inductor is a type of fixed inductor, which is ideal for high frequency use in power line circuit as well as for low-frequency applications. This inductor is characterized by having low DC resistance and low leakage inductance. It also has a high current rating and an excellent temperature coefficient.

Application Field

The L0201R82AHSTR Inductor is suitable for voltage regulator circuits, power supplies, switching power supplies, DC/DC converters, step-down converters, amplifier circuits, and radio-frequency circuits. It can also be used in automotive electronic applications, industrial control systems, and in communications and computing systems.

Working Principle

When an alternating current flows through the inductor, an alternating magnetic field is created in the form of a coil. This alternating magnetic field generates a counter-electromotive force, which is opposite to the direction of the current. The inductance thus generated is known as the "inductive reactance" of the inductor.

The inductive reactance of the inductor is responsible for the electrical energy that is stored and released as electric current. Depending on the current flow through the inductor, the electric current is either increased or decreased. As the applied voltage is increased, the induced current also increases. This is because the inductive reactance is a linear function of the applied voltage.

In addition, the L0201R82AHSTR Inductor is designed to withstand high temperatures and voltage changes so that it can be used in a range of thin-film devices and integrated circuits. The performance of the inductor can also be improved by designing its core in a rectangular shape, which reduces the effects of magnetic saturation. As a result, the performance of the inductor is more efficient and requires less current for its operation.

Conclusion

In conclusion, the L0201R82AHSTR Inductor is a specialized type of fixed inductor which is designed to provide high impedance with low DC resistance and leakage inductance. It is ideal for high-frequency applications, such as power supplies, DC/DC converters, step-down converters, and amplifier circuits. With its rectangular core, it can provide high efficiency with less current, making it perfect for integrated circuits and thin-film devices.
