LQG18HN47NJ00D

Fixed inductors are electromechanical devices used within electronic circuits to store and release energy at a frequency rate. LQG18HN47NJ00D is one type of fixed inductor often used in many applications. In this article, we will discuss the application field and working principle of this device.

Application Field

The LQG18HN47NJ00D device is mainly used in power conversion circuits such as AC/DC or DC/DC converters, providing good linearity over wide current and frequency ranges. They are also suitable for filtering and rectification in communication circuits. Since this device has a high current-handling capability, it is also often used in the automotive industry where high currents are generated.

Also, it is commonly used in high-power motor drives and power-conditioning equipment like LED drivers, making it perfect for a variety of vehicular and consumer applications like brakes, steering and electronics.

Working Principle

The LQG18HN47NJ00D device is based on the principle of inductance, where electric current is generated in a winding of copper wire when exposed to a changing magnetic field. This produces an electromagnetic field which interacts with the electric current passing through, generating additional current or voltage.

The device works by storing and releasing energy at a frequency rate, and is composed of two winding layers. The external field causes an electric voltage to be induced in a secondary winding, resulting in an internal power supply. The secondary winding can also be used to steer current flow to other parts of the circuit.

The two winding layers allow the device to produce high current output with good linearity over a wide frequency range. In addition, its low equivalent series resistance (ESR) feature enables it to handle high currents without heat dissipation.

Conclusion

The LQG18HN47NJ00D is a type of fixed inductor, and is perfect for use in power conversion circuits, LED drivers, motor drives, and other industrial and consumer applications. It operates on the principle of inductance, with a secondary winding supplying extra assistance when needed. The device has good linearity over wide current and frequency ranges, and is able to handle high currents without generating too much heat.
