Fixed-value inductors, generally referred to as inductors, are widely used in various electronic circuits. SPM4020T-100M-LR is one of the fixed inductors with excellent performance. This article will discuss the application field and working principle of the SPM4020T-100M-LR inductors.

The SPM4020T-100M-LR inductors are used in radio frequency (RF) applications due to their small size and good high-frequency characteristics. Because of the high-frequency performance, these inductors are used in many circuits such as voltage-controlled oscillators, power conversion circuits, and switching power supplies, etc. Furthermore, the inductors are used in high-frequency RF and microwave circuits in communication and other applications. These inductors have high inductance values and are suitable for power applications.

The working principle of SPM4020T-100M-LR inductors is based on the phenomenon of magnetic flux linkage. When a current passes through the inductor, a magnetic field is created, and this magnetic field links together with the current, resulting in an increase in the inductance of the component. The magnetic field will also affect the adjacent windings, thus increasing the inductance of the inductor. The amount of the inductance is determined by the number of turns in the coil, the size of the coil, and the amount of current passing through it. The higher the current, the higher the inductance.

The SPM4020T-100M-LR fixed inductors are composed of high-frequency ferrite core materials, which can provide good high-frequency characteristics. This inductor can normally operate at temperatures ranging from -40 to +85°C which make them highly suitable for RF power applications. The inductor has a rated impedance of 100 mOhm and its inductance range is from 0.4 to 0.6µH. The leakage inductance is very low, minimizing any noise and interference which make it ideal for high-frequency applications.

In conclusion, the SPM4020T-100M-LR fixed inductors are used in a wide range of applications, because of their excellent performance and long operating life. The working principle of these inductors is based on the magnetic flux linkage phenomenon, which allow them to have higher inductance values. Furthermore, the inductors also have good high-frequency characteristics and a rated impedance of 100 mOhm. These features make the SPM4020T-100M-LR inductors highly suitable for high-frequency power applications.
