LQW15AN8N7G00D is a type of fixed inductor. It is a passive component as an inductor and part of an electrical circuit, designed to resist changes in the electric current or its associated magnetic field in a circuit where the current is alternating. In other words, the inductor opposes changes in the flow of electric current and stores energy in the form of a magnetic field. The inductor is made up of a wire wound either onto a coil or frame with a core of air, ferrite, powdered iron, or a combination of both. The winding material and core material depends upon the frequency of operation of the inductor and the amount of current that needs to be passed through it. This type of inductor is suitable for operating in high currents, high frequencies, or in a high temperature environment.

The LQW15AN8N7G00D fixed inductor is used in applications such as automotive, consumer electronics, LED lighting, etc. It is a PC board (Printed Circuit Board) product that can be used as an input or output filter component, to help minimize noise and decrease spurious signals. It has an inductance value of 4700uH and a rated current of 1.3A. It has a low resistance of 4mΩ and a high self-resonant frequency of 1.8MHz. The type of inductor has a high temperature range of -40 to +85°C and a power dissipation of 1.6W. It is a SMD (Surface Mount Devices), which offers excellent performance in the given temperature range. It has an operating temperature of -55° to +125°C.

The working principle of a fixed inductor is the same as any other inductor. When a current is applied, a magnetic field is created around the wire windings, which stores energy in the form of an electromagnetic field. As the current increases or decreases, the electromagnetic field increases or decreases accordingly. This change in field strength (induced flux) generates voltage which opposes the applied current, according to Lenz’s law. This voltage induced across the inductor is commonly known as back emf which is in opposition to the applied voltage. It is also called voltage drop since it reduces the total circuit voltage. The back emf generated increases with the inductance of the component.

Due to the inductive nature of a fixed inductor, it is advisable to use them in low frequency applications such as DC power supply systems or AC power supply systems that alternate at a lower frequency. They can also be used in high frequency applications where high frequency signals need to be filtered out and noise cancellation is of prime importance. The LQW15AN8N7G00D fixed inductor is also used in the implementation of DC-DC converters, where it helps to reduce the noise in a circuit.

In summary, the LQW15AN8N7G00D is a kind of fixed inductor that is widely used in automotive, consumer electronics, and LED lighting applications. Its rated current is 1.3A, its inductance value is 4700uH, and it has a low resistance of 4mΩ. It has a high temperature range of -40 to +85°C and its power dissipation is 1.6W. Its working principle is based on Lenz\'s law, where the back emf generated opposes the applied voltage. This inductor is suitable for both high frequency and low frequency applications.
