Fixed inductors are devices that are designed to provide a fixed inductance in an electrical circuit, with ATFC-0201HQ-0N8B-T being a representation of the type of fixed inductors available in the market. It utilizes a form of inductive element known as a ferrite bead which is a completely sealed and encapsulated magnetic core of ferrite material. In this article, we\'ll discuss the application field and working principle of the ATFC-0201HQ-0N8B-T fixed inductors.

The ATFC-0201HQ-0N8B-T is primarily used in EMI/RFI and ESD suppression applications, and is useful for radio noise suppression in audio equipment due to its ability to effectively reduce electrical noise while also providing wide frequency suppression. Its ability to withstand high temperatures makes it suitable for use in high temperature environments and it also has a high current limit. The inductor has a ferrite core and a diameter of 0.2 inches, so it can easily be mounted and soldered on a PCB.

The working principle of ATFC-0201HQ-0N8B-T is based on the principle of electromagnetic induction. This is a phenomenon in which the induced electromotive force (emf) is created in a closed conductor when there is relative motion between the conductor and the surrounding magnetic field. The emf induced is proportional to the rate of change of flux linkage with respect to time, and can be written as $E= -N\frac{d\phi}{dt}$, where $N$ is the number of turns in the conductor and $\phi$ is the flux linking it. By winding a conductor around a ferrite core, a coil can be formed which can be used to create a fixed magnetic field, thus enabling the coil to act as an inductor.

In the case of the ATFC-0201HQ-0N8B-T, the ferrite core has a higher relative permeability compared to air, thus enabling it to concentrate the magnetic flux lines in the core, thereby increasing the inductance. This phenomenon is known as magnetic saturation, and it is the property coupled with the ferrite core that enables the ATFC-0201HQ-0N8B-T to exhibit a high degree of inductance. Thus, the working principle of the ATFC-0201HQ-0N8B-T is that of inducing a fixed amount of current into a conductor by exploiting the properties of magnetic saturation in a ferrite core.

Applications for ATFC-0201HQ-0N8B-T include EMI/RFI shielding, signal filtering, and protection from Electrostatic Discharge (ESD). It is commonly used in automotive, consumer electronics, telecommunication, and medical devices. The ATFC-0201HQ-0N8B-T can be used to filter out unwanted noise and signals from other components, allowing only the desired signal to be detected. Furthermore, the inductor has a high current limit, making it suitable for applications that require high current management.

The ATFC-0201HQ-0N8B-T fixed inductor is a highly effective device for EMI/RFI and ESD suppression applications. Its ferrite core provides excellent magnetic saturation, which can be used to induce an effective inductance into a conductor. Furthermore, its high current limit makes it suitable for use in high current applications. This, coupled with its suitability for high temperature environments, makes it an ideal choice for numerous applications.
