Fixed inductors, the basic components of circuits, play an important role in playing a major position in many electronic circuits. The B82422A1222K100 is a type of fixed inductors in the field of electronic components. It is widely used in various electronic applications. This article will discuss the application field and working principle of B82422A1222K100.

The B82422A1222K100 is a toroidal inductance type, with three terminals. It has high current carrying capacity and low DCR. Its inductance range is between 1uH and 100uH. The rated voltage of the inductor is 25VAC, with peak current up to 2.8A. It can meet the requirements of high current in high frequency applications. This type of inductor is mainly used in low frequency circuits and power supplies, such as a variety of power adapters. Besides, it is also used in LED drives, consumer electronics, automotive industry, and industrial control.

The structure of B82422A1222K100 comprises of a closed core, a winding wire on the core, a damping sheet, and its output terminal. The core of the inductor is made of ferrite which can increase the inductance value to tens of sub-microhenrys. Usually, the structure between the winding and the core is fixed through gluing and other pressure generating and retaining methods. A damping sheet is also used to reduce the influence of harmonic currents in the winding, resulting in less temperature rise. The output terminals of the inductor are connected externally to the DC circuit so that the power supply can be brought into, and output from the inductor.

The working principle of B82422A1222K100 is based on Faraday\'s Law of electromagnetic induction. When electric current runs through the winding wire on the core, a magnetic field is generated. This magnetic field can induce an electromotive force (EMF) in the winding and a reverse current is created. The EMF is represented by the voltage differences between the input and output terminal of the inductor. Meanwhile, by the law of current conservation, the total current through the inductor will remain constant. Therefore, the inductance of the inductor produces the effect of “self-induced circuit".

In summary, B82422A1222K100 is a type of fixed inductor, which is mainly used in applications such as power adapters, LED drives, consumer electronics, automotive industry, and industrial control. Its inductance, voltage, current capacity, and temperature range are specificed in the product catalogue. The working principle of the B82422A1222K100 is based on Faraday\'s Law of electromagnetic induction. Its core and winding wires create a magnetic field which induces an electromotive force, resulting in a reverse current through the output terminals of the inductor.
