The fixed inductor, or inductor, is a vital component of any contemporary circuit used in the electronics industry. It is commonly available in surface mounted components (SMCs) or as through-hole discrete components. It consists of two or more windings of conductive material, such as copper, wound around a core made of conductive ferrite, cermets, air or ferromagnetic material.

The LQM21NNR15K10D is a surface mounted fixed inductor. It works on the principle of magentic field induction. The inductor is particularly capable of high current operation, with low losses in high frequency circuits. With a wide range of inductance values, from 10nH to 10µH, the LQM21NNR15K10D can be used in a broad variety of circuits and applications.

The main application field of the LQM21NNR15K10D is in high-frequency power supplies. This is because it is exceptionally efficient in high frequency applications, with a low power dissipation and a low temperature rise when used in these high-frequency circuits. It is also suitable for use in portable wireless power solutions, adapter circuits, notebook computers, telecom devices, LED lighting, audio processing and even navigational systems.

The working principle directly relates to the magnetic field induction. Essentially, when electric current passes through the inductor, it produces a magnetic field according to Faraday\'s law of induction. This magnetic field then attracts and repels the area around it. As electric current flows through the inductor, the repelling force feedback in the form of an electric current, thus inducing a reverse electric field in the inductor winding.

The resulting induced electric field is then further dissolved through the external connection of the inductor with power rails. This induced electric field is not only proportional to the electrical current, but also to the rate of the occurring changes of the electrical current. Hence, an inductive nature is created through the use of the LQM21NNR15K10D. In addition, its excellent power dissipation characteristics allow the component to be paired with capacitor packages in order to create filter circuits as well.

In summary, the LQM21NNR15K10D is a surface mounted fixed inductor designed to be highly efficient in high-frequency powering solutions. Its main application area is in the electronic industry, such as in power supplies, adapter circuits, notebook computers, telecom devices, LED lighting, audio processing and navigational systems. This inductor works on the principle of magnetic field induction, which produces a repulsion of the area around it when power passes through it. This repulsion results in the induction of a reverse electric field. Finally, its excellent power dissipation and low temperature rise make it a highly efficient and reliable choice for modern circuitry designs.
