Fixed Inductors: LQW15AN72NG00D Application Field and Working Principle

Introduction

Fixed inductors, also known as inductors, are basic electrical components widely used in various electronic circuits. The space saving and reliable LQW15AN72NG00D fixed inductor, made in conformity with the SMD type package, is created to reduce noise and offer stability in the electrical system.

Application Field

This product provides low-loss performance even in high frequency circuits, which makes it suitable for various industries like computing, telecoms, automotive, consumer electronics, and medical devices. The LQW15AN72NG00D is a fairly popular product in the industry. Its high quality, reliable performance and competitive price have made it a favorite choice when it comes to assembling a reliable, large-scale circuit. Within computing industry, such product can be used in motherboards, disc drives, servers, and notebooks. LQW15AN72NG00D can also be utilized in producing a reliable AM/FM reception system in car audio appliances. Telecommunication devices like modems, televisions, and base stations could also benefit from using this pre-tapped inductor because of its low Q Treble performance. It can also be used in a wide array of consumer electronic products, for instance, DVD players and players, digital cameras, portable media players, and so on. It is also applicable in medical devices such as hearing aid, ECG and cardiopulmonary respiration equipment.

Working Principle

The LQW15AN72NG00D fixed inductor is essentially an inductor consisting of two parts -- the coil and core that together form a circuit that enable a current to flow. The core is normally made from Iron-based alloy, that helps improve the efficiency of the inductor. The coil, on the other hand, is made of cylindrical windings of copper wire which allows electric current to flow in one direction.When an electrical current is passed through the coil, an electrical field is generated which interacts with the magnetized core to create a magnetic field. This magnetic field will induce a voltage in the windings of the coil in the opposite direction as the current that created it. This is known as electromagnetic induction.Their working principle is the same as that of a transformer - when the current is increasing in the coil, the flux of the core increases in the same ratio, inducing a voltage in the windings. As the current decreases, the flux in the core also decreases and produces a voltage in the opposite direction of the current. This is known as a counter EMF. The LQW15AN72NG00D is designed to have a high Q factor so that it can support high frequency applications.

Conclusion

The SMD-Packaged LQW15AN72NG00D Fixed Inductor is designed based on the core principle of Faraday\'s law and performs a wide variety of tasks across many different industries. The product has some advantages over the other types of inductors or transformers because of its small size, low-loss, and high-frequency performance. With its reliable performance, this great product has become one of the favorites of many industries.
