Fixed inductors are a type of inductor that works by storing energy into a magnetic field for later use. In this article we will discuss the application field and working principle of the 4379R-394JS fixed inductor.

Application Field

The 4379R-394JS fixed inductor is mainly used in power electronic applications, such as high-frequency switching power supplies, switching power converters, and adjustable speed drives. It is also used as a component in resonant circuits and filters. Additionally, the inductor is used in communication equipment such as mobile phones, computers, and other electronic appliances.

Working Principle

The 4379R-394JS fixed inductor works by converting electrical energy to a magnetic field. This is done by passing a current through a wire that is wound in a coil, thus creating a magnetic field in the wire. The wire’s inductance is proportional to the number of turns in the coil, the magnetizing force, and the area of the coil. When the current in the coil is changed, the magnetic field also changes, which induces a changing voltage in the coil. This voltage is then used to power an electrical device. Additionally, the inductor has an air gap in the core, which causes the magnetic field to be concentrated in the core instead of being scattered across the entire coil.

Furthermore, the inductor also has a “saturation characteristic” which means that it can only store so much energy before it starts to saturate. When the inductor is saturated, the magnetic field becomes stronger, increasing the inductance of the coil, thus allowing it to store more energy. The inductor is also capable of storing energy at a higher frequency than other types of inductors, which makes it ideal for use in high-frequency applications.

In summary, the 4379R-394JS fixed inductor is a type of inductor that is mainly used in power electronic applications, such as high-frequency switching power supplies, switching power converters, and adjustable speed drives. It works by converting electrical energy to a magnetic field, which is then used to power an electrical device. Additionally, the inductor has an air gap in the core, which causes the magnetic field to be concentrated in the core instead of being scattered across the entire coil. Moreover, the inductor also has a “saturation characteristic” which means that it can only store so much energy before it starts to saturate.
