Fixed inductors, like the LQW18AN69NJ8ZD, are electrical components that store energy in the form of a magnetic field when exposed to a current. Commonly found in power supplies and audio frequency circuits, they are composed of a coil of wires embedded in a ceramic, plastic, or ferrite core which affects the devices magnetic properties and increase its inductance.

The working principle behind fixed inductors is that of Faraday\'s Law of Induction, which states that when a conductor is exposed to a changing magnetic field, an electric field is created around it. This electric field causes a current to flow, which in turn creates its own magnetic field in the opposite direction. This second magnetic field opposes the original, resulting in a varying voltage in the conductor, known as inductance. Therefore, when a direct current is passed through the inductor, the magnetic field created by the current is stored within the device, effectively ‘storing’ energy.

As such, the application of LQW18AN69NJ8ZD fixed inductors depends on their ability to store energy, aiding in the stabilization and filtering of circuit outputs. This is commonly be seen in the regulation of voltage spikes in audio circuits, by creating local magnetic fields of a certain strength so that alternating current is distorted, and only a certain frequency is allowed to pass through. Fixed inductors are also used in power supplies, speeding up or slowing down an input signal and helping to filter out any unwanted noise.

In summary, fixed inductors such as the LQW18AN69NJ8ZD serve to store energy, in the form of a magnetic field, when exposed to a direct current. This allows them to be used in power supplies and audio frequency circuits, to regulate voltage spikes and filter out unwanted noise.
