Fixed Inductors

Fixed or non-variable inductors are electrical components which use magnetic fields to control the flow of current through electric circuits. A 79F121K-TR-RC is one type of fixed inductor. This article will explore the application field and working principle of the 79F121K-TR-RC.

79F121K-TR-RC Application Field

The 79F121K-TR-RC is used in a variety of applications. These include signal conditioning in audio amplifiers, smoothing circuits, DC-DC converters, switching power supplies, pulse transformers, and more. This type of inductor is especially popular in mobile applications such as laptops and tablets due to its low profile.

79F121K-TR-RC Working Principle

The 79F121K-TR-RC is a type of non-variable inductor which works on the same principle as all other inductors: it creates a magnetic field around the winding which can store and release energy to control the flow of current in an electric circuit. This magnetic field is generated by an electric current flowing through the windings of the inductor.When a steady current is passed through the inductor, it generates a steady magnetic field which then stores the energy in the form of a magnetic field. When this current is removed, the stored energy is released, thus producing a current in the opposite direction. This reverse current, also known as a back EMF, can be used to modify the current in a circuit and is the basis of the 79F121K-TR-RC working principle.

Conclusion

The 79F121K-TR-RC is a type of fixed inductor which is popular in mobile applications due to its low profile. It works on the same principle as all other inductors, creating a magnetic field around its windings which can store and release energy to modify the current flow in an electric circuit. This back EMF is the working principle of the 79F121K-TR-RC and is used in a variety of applications, such as signal conditioning, smoothing circuits, and others.
