Fixed inductors are electrical components that store energy in the form of magnetic fields. They work by transferring and receiving energy between two points, usually in the form of voltage or current. An inductor has two terminals, one for the supply of voltage or current and the other for the return of energy. Typically, they are used for AC circuits, but DC circuits are also possible. The LQP02HQ13NJ02E is a fixed inductor used for DC and AC applications, and its working principle is based on Faraday\'s law of induction.

Faraday’s law of induction states that whenever the flux through a circuit changes, an electromotive force (emf) is induced in the circuit. This emf is also known as the counter electromotive force (CEMF). This phenomenon is used in the LQP02HQ13NJ02E fixed inductor to store and release the energy as the current rises and falls. This is done by coupling the two inductors together so that the AC and DC currents respectively induce an emf in each other. The current in each inductor is then set by the voltage difference between them. In other words, the inductance of the combined inductors is determined by the voltage between them.

The LQP02HQ13NJ02E fixed inductor is thus useful for DC and AC circuits. In AC circuits, the inductor can be used as a current transformer, a voltage transformer, a power factor meter, or any other type of current sensing application. In DC circuits, the inductor can be used as a filter, a clamp for protection against surges, or as a common mode chokes. The use of this inductor in DC circuits depends on the rating and type of the inductor, which is chosen based on the operating voltage and current of the application.

Furthermore, the LQP02HQ13NJ02E fixed inductor can also be used in various RF applications. In these applications, the inductor’s self-resonance frequency determines the frequency range and the impedance of the circuit. This frequency is determined by the series capacitance of the inductor, and affects the reactance of the inductor and how it behaves in the circuit. These parameters determine the filtering and attenuation properties of the inductor in RF applications. Therefore, the LQP02HQ13NJ02E fixed inductor is suitable for applications where impedance matching is required.

In conclusion, the LQP02HQ13NJ02E fixed inductor is a useful component for applications in DC and AC circuits, as well as RF applications. Its working principle is based on Faraday’s laws of induction, and the inductor’s frequency and impedance parameters determine its filtering and attenuation characteristics in RF applications. Therefore, it is highly versatile in its uses, which makes it a valuable component for electronics engineers.
