Fixed inductors play a key role in the electrification of many electronic equipment. They form part of the energy-conserving devices that reach power electronics systems such as power supplies and UPS systems. This article focuses on the specific fixed inductor, the HKQ04020N8C-T, and discusses the application field and working principle.

Application Field

The HKQ04020N8C-T fixed inductor is suitable for a wide variety of fields with regard to frequency and power. For example, it is ideal for use in such applications as low noise power supplies, DC/DC converters, portable communications and auto electronics, and other high performance products. It is particularly well suited for applications that require a very small form factor and low electromagnetic interference due to its low height.

Furthermore, the HKQ04020N8C-T is a through-hole inductor that offers numerous advantages in such fields as filtering, wireless power transmission, and energy conversion efficiency. It increases both signal stability and signal throughput in these applications.

Working Principle

The working principle of the HKQ04020N8C-T fixed inductor is the same as that of all inductors. The primary principle is the relationship between electrical current and magnetic field, known as Faraday\'s Law. This law states that the magnitude of induced electromotive force (EMF) is proportional to the time rate of change of the magnetic flux. Put simply, the device takes in electrical energy and converts it to a magnetic field.

In the case of the HKQ04020N8C-T, the magnetic field is stored in a series of coils with the help of a ferromagnetic material. When an electrical current is applied, the coils become energized and a magnetic field is created. During this process, energy is stored in the magnetic field, and this energy is released when the current is changed or removed.

This device also takes advantage of the skin effect, also known as the eddy current effect. In essence, it takes in current on the surface of the core at the highest frequencies and, in so doing, eliminates losses. This reduces heat build-up and ensures maximum efficiency.

Conclusion

The HKQ04020N8C-T fixed inductor is a highly efficient and reliable device with a wide range of applications. It focuses current on its surface at high frequencies and stores this current in an electromagnetic field. This device is very useful for high performance electronics applications and can help to achieve improved signal stability and signal throughput.
