Fixed Inductors

Inductors are passive components used in all types of electrical circuits. They allow for current and voltage regulation, signal filtering, and transformer coupling. Fixed inductors are integrated circuit components designed for specific applications, such as supporting the resonance of an oscillator, providing noise suppression, or generating a stable low-frequency signal. Among many inductors, IHB4BV820K is a popular fixed inductor specifically designed for power supply applications. This article will discuss the application fields and working principle of IHB4BV820K in detail.

Application Field of IHB4BV820K

IHB4BV820K is a fixed inductor specifically designed for power supply applications. It consists of a ferrite core with an air gap and two or three windings. It is primarily used to filter electromagnetic interference (EMI) and limit the transient peak current in the power line. It supports the resonance of an oscillator circuit, eliminates noises, provides stable low-frequency signals, and filters unwanted frequencies and harmonics in the signal. Additionally, it provides better EMI protection and power saving performances than other types of inductors, and can be used to reduce noise on power supplies, computer circuits, and communication lines.

Working Principle of IHB4BV820K

IHB4BV820K works on the principle of magnetic field induction and Faraday\'s Law of Electromagnetic Induction. Electromagnetic induction is a process in which a conductor, such as a wire, when in the vicinity of a magnetic field, will generate an induced current. Therefore, when an alternating current flows through an inductor, a magnetic field is generated in the core of the inductor and this field induce a voltage in the winding. This induced voltage opposes the current, resulting in an inductance in the circuit. In the case of IHB4BV820K, the inductance is generated by the ferrite core and windings, and the air gap allows for better control of the inductance value. When an alternating current flows through the inductor, a voltage is induced in the winding which will oppose the current. This inductance reduces the current flow, preventing it from reaching the expected peak value. As a result, it helps to filter interference frequencies and eliminate noise in the power supply.

Conclusion

In conclusion, IHB4BV820K is a fixed inductor specifically designed for power supply applications. It provides better EMI protection and power saving performances than other types of inductors and can be used to reduce noise on power supplies, computer circuits, and communication lines. It works on the principle of magnetic field induction and Faraday’s Law of Electromagnetic Induction by creating an inductance in the circuit which prevents the current from reaching the expected peak value. Therefore, it helps to filter interference frequencies and eliminate noise in the power supply.
