PL8604

Fixed inductors refer to inductors that are composed of wrapped enameled wire and magnetic core components, and their inductance is fixed. PL8604 is a kind of fixed inductor. It is composed of enameled wire, ferrite core and other components. Its main application field is wireless communication. This article will explain the application field and working principle of the PL8604.

Application field

The PL8604 fixed inductor has a wide range of applications in wireless communication, including LTE, 3G, GSM, WiMAX, RFID and etc. For example, it is widely used in power amplifiers and switches for GSM mobile phone base stations, and in LTE base station power amplifiers. It can also work in wireless communication system on multiple frequency bands, providing high precision inductors. In addition, it can also be used in the power supplies of various communication equipment.

Working principle

The basic working principle of the PL8604 is based on the principle of electromagnetic induction. When an alternating current passes through the inductor, it generates a magnetic field. When the magnetic flux passes through the winding composed of enameled wires, it will induce an electromotive force, resulting in a current which is in phase with the external alternating current. According to Faraday\'s law of induction, the induced electromotive force and the resulting current are proportional to the rate of change of the magnetic flux.

The ferrite core of the PL8604 can effectively concentrate the magnetic field created by the enameled wire to increase the magnetic flux. In this way, the inductance of the inductor can be increased, and corresponding changes in the resistance value and reactance can also be made. The strength of the magnetic field affects the properties of the inductor, which determines the performance of the inductor, such as Q value, frequency, inductance and so on.

Conclusion

The PL8604 is a high performance fixed inductor, which is widely used in wireless communication systems such as GSM, LTE and WiMAX. Its main working principle is based on the principle of electromagnetic induction, and its ferrite core greatly enhances its performance. Understanding its working principle and application field is of great benefit to its use in engineering.
