Fixed Inductors

Inductors are one of the simplest yet significant passive components used to filter, encode, and digitally process signals in electronic circuits. Fixed inductors are the most common type of inductors found in these circuits, and the LQW18AN11NG80D is a prime example of a successful fixed inductor. This document will explore the application fields and working principles of the LQW18AN11NG80D fixed inductor.

Application Fields of the LQW18AN11NG80D

The LQW18AN11NG80D is a fixed type inductor primarily used in the radio frequency (RF) industry because it has excellent RF/microwave performance over a wide frequency range. It is designed with several characteristics that make it favorable for RF applications, such as a high inductance-to-loss ratio, tight tolerances, and high current-handling capability provided by its multilayer construction. As a result, the LQW18AN11NG80D is found in such RF components as oscillators, amplifiers, mixers, filters, antenna switches, and baluns.

Other application fields of the LQW18AN11NG80D include high frequency switching power supplies, RF remote controllers, sound systems, and short-haul video distribution systems. Its high current-handling and low environmental stress make it a suitable choice for these types of applications.

Working Principle of the LQW18AN11NG80D

At its core, the LQW18AN11NG80D fixed inductor works according to Faraday’s Law of Induction. This law states that when an electric current is applied to a conductor, an electromotive force is induced in the conductor. This force is known as a voltage, and its magnitude and direction are determined by the magnitude and direction of the applied current and the number of turns per unit length of the conductor. Therefore, when the current in the LQW18AN11NG80D changes, its voltage output also changes, and this results in an induced current in the primary winding of the inductor.

The current in the LQW18AN11NG80D’s secondary winding is then proportional to the rate of change of the current in the primary winding. In other words, the LQW18AN11NG80D acts as a transformer, and its induced voltage output is typically used to amplify or attenuate signals in RF components.

The LQW18AN11NG80D also utilizes axial leads, which are leads that run parallel to the current flow, to transfer the induced current from its primary winding to its secondary winding. This is beneficial for RF applications because it ensures the inductor’s internal components are tightly sealed, thus preventing unnecessary electromagnetic interference.

Conclusion

The LQW18AN11NG80D fixed inductor is a powerful and versatile component for RF applications. It is capable of handling high current, performing well over a wide frequency range, and providing low environmental stress. Its applications include RF components such as oscillators, amplifiers, mixers, filters, antenna switches, and baluns, as well as high frequency switching power supplies, RF remote controllers, sound systems, and short-haul video distribution systems. The working principle of the LQW18AN11NG80D is based on Faraday’s Law of Induction, and its axial leads help to keep the internal components of the inductor tightly sealed.
