Fixed inductors are electronic components which use a coil of wire to create an alternating current or electromagnetic field. The 4379-824KS is a series of fixed inductors made by Coilcraft that are designed for a variety of applications in different industries. This paper will discuss the application field and working principle of the 4379-824KS.

The 4379-824KS is a series of inductors that are especially useful for switching regulator applications. They use a unique construction consisting of a string of ferrite beads around a single winding in order to provide a low-cost solution for low current applications. The ferrite beads help to minimize EMI (electromagnetic interference).

The 4379-824KS has a wide range of applications in different industries. It can be used for high frequency resonant converters, such as those used in power over Ethernet and AC/DC switching supplies. It is also used in automotive circuits, and in telecommunications and consumer electronics applications. The 4379-824KS is widely used for impedance-matching and filtering applications.

The 4379-824KS works on the principle of inductive reactance. Reactance is the opposition to the flow of alternating current in an inductor. It is caused by the inductor\'s artificial creation of an electromagnetic field around the conductor in the coil when current is applied. This electromagnetic field induces a counter force, or reactance, in the conductor that opposes the flow of current through it.

In this way, the 4379-824KS series of fixed inductors uses the principle of inductive reactance to achieve its functionality. It has a unique construction with a single winding surrounded by a string of ferrite beads that minimizes EMI. This allows for high-frequency resonant converter and impedance-matching applications in different industries, from automotive and consumer electronics to power over Ethernet and AC/DC switching supplies.

In summary, the 4379-824KS is a series of fixed inductors designed by Coilcraft for various applications in different industries. Its unique construction, consisting of a single winding surrounded by ferrite beads, not only provides a low-cost solution for low current applications but also helps to minimize EMI. Its application field spans automotive, consumer electronics, telecommunications, and power over Ethernet, among others. Finally, it works on the principle that its inductive reactance creates a counter force in the conductor to oppose the flow of alternating current.
