Fixed Inductors

Inductors are useful components in electrical engineering, used for a variety of tasks from filtering to matching impedance. A fixed inductor is an inductor whose inductance value does not change or can only be adjusted within a very small range. A 2890-20F Inductor is a fixed inductor designed for use in industrial, scientific and medical (ISM) applications, resulting in a variety of potential use cases.

Application Field

The 2890-20F Inductor\'s application field is closely related to its inductance value. This particular inductor is 5.2mH, which is perfectly suited for applications requiring precision control of the resonant frequency, such as radio-frequency (RF) circuits, antenna couplings, and power supplies.Thanks to its high inductance density, the 2890-20F is well-suited for use in circuits requiring high inductance values in a small package. In short, its application field is very broad: any circuit that requires low-loss, high-frequency performance can benefit from the 2890-20F Inductor.

Working Principle

The 2890-20F Inductor works on the same principle as other fixed inductors: it creates a magnetic field around it by conducting an electrical current. This magnetic field can then be used to store energy in the form of magnetic flux, which can be used to regulate current flow. The amount of energy that a particular inductor can store is determined by its inductance value. The higher the inductance value, the more energy the inductor can store. The 2890-20F Inductor has a high inductance value, making it ideal for applications requiring a large amount of energy storage.The 2890-20F Inductor also has a low DC resistance, which is essential for applications requiring high-frequency operation. This low resistance allows it to achieve higher efficiencies and lower noise levels than other inductors. Additionally, it features an epoxy resin-sealed construction, which makes it impervious to moisture and allows it to operate in harsh environments.

Characteristic

The 2890-20F Inductor’s characteristic helps to further explain how it works in various applications. It has a very low DCR, which improves its power efficiency and helps reduce noise levels. Its high permeability helps it to achieve higher inductance values while maintaining a small size. Its high self-resonant frequency also enables it to be used in higher-frequency applications. Finally, its epoxy resin sealed construction makes it moisture and temperature resistant, allowing it to operate reliably in harsh environments.

Conclusion

In conclusion, the 2890-20F Inductor is an invaluable component for industrial, scientific, and medical applications. Its application field is broad, thanks to its high inductance density, low DCR, and epoxy resin-sealed construction. Furthermore, its high permeability and self-resonant frequency further widen its potential applications. All of these characteristics combine to make the 2890-20F Inductor an ideal solution for a variety of uses.
