Fixed Inductors are devices used in countless electrical circuits for a variety of different purposes. The 4379-155JS is a particular type of fixed inductor widely used in the commercial and industrial environments. In this article, we’ll cover its application field and outline its primary working principle.

What Is the 4379-155JS?

As already mentioned, the 4379-155JS is a particular type of fixed inductor, part of the larger family of electromagnetic components. It is characterized by a particular size and construction that give it a specialized purpose (for more on inductors in general, check out this Wikipedia article). More specifically, this inductor has:

• A current rating of 10 Amps
• A case size of 5.9 x 5.4 x 3.9mm
• A copper-crimped ferrite core
• An available inductance range of 0.1 – 10µH

Essentially, the 4379-155JS is an efficient and relatively cheap type of component that is well-suited to a wide variety of applications.

The 4379-155JS in Action: Application Field and Working Principle

Application Field

This type of inductor is widely used in many different electrical circuits, including:

• Switch Mode Power Supply (SMPS) circuits
• RF Filter circuits
• Automatic Frequency Control (AFC) circuits
• High Frequency Conversion circuits
• Mobile Phone circuits
• Motor Blocks circuits
• Multi-Function circuits

Its small dimensions make it well-suited to implementation in tight spaces. Furthermore, its low cost and high current rating make it an attractive target for electrical designers.

Working Principle

Its specialized construction, featuring a copper-crimped ferrite core, makes this type of inductor uniquely suited to its application field. The core contains a wire, usually insulated copper, that has been ‘crimped’ around it – this setup is kept in place due to the strong magnetic fields created by the core.

When an AC current is applied to the primary winding of the inductor, and a second winding is connected to a load, the physical current is transferred through the induced windings. This is possible due to the electromagnetic field generated between the core and the coils. This field allows electrons to transfer through the core – hence the device’s ability to transfer current.

Essentially, its working principle utilizes the fact that, when a current is applied to an inductor, the magnetic field will generate an equal and opposite side-effect. This side-effect is what allows energy to be transferred to the load.

Conclusion

In this article, we have explored the 4379-155JS fixed inductor and its application field. We outlined its advantages (such as its small size and low-cost) and explained its working principle (which fundamentally relies on the law of induction). We hope that this information has given you an insight into the capabilities of this versatile and reliable type of inductor.
