Fixed inductors are one of the most important components in an electronic system, used in a wide variety of applications. The SD3814-4R7-R is a fixed inductor that is ideal for use in such applications. This inductor is a simple and cost-effective way to provide the necessary inductance in circuits. It is a low cost and high quality solution for meeting the requirements of high frequency design.

The SD3814-4R7-R is a very versatile part. It is capable of supplying a wide range of inductance values, ranging from 4.7 microhenrys up to 0.25 micro henrys. This range of values also allows it to be used in a variety of applications, from low- power/low-frequency digital circuits to high- power/high-frequency analog/RF designs. The inductor has a low DC resistance which makes it suitable for use in high-voltage environment.

SD3814-4R7-R inductor’s application field primarily consists of high-power switching, voltage regulation, signal conditioning, and rectification applications. It is also used in LED lighting systems, LED module, and electronic ballast applications. As it supports a wide range of inductance values, it can be used to form distributed and pair inductors. It also provides enhanced inductance-adjustment range and improved inductance stability in switching applications.

The working principle of SD3814-4R7-R is based on magnetic field in which AC current forms a magnetic field around the inductor windings. This induces an opposing magnetic field which induces a back EMF (Electromotive Force) in the windings. This back EMF opposes the change in current flow and increases its magnitude, thus limiting the speed of current increase. This is what causes inductance. The magnitude of the inductance depends on the number of turns in the inductor’s winding, its core material, and its geometry.

Besides, the material of the core also plays an important role as it affects the permeability, which in turn affects the inductance. The SD3814-4R7-R uses a ferrite core, which provides excellent frequency response and low core loss. This also makes the part very suitable for use in high-frequency applications.

Overall, the SD3814-4R7-R provides a cost-effective solution for providing the required inductance in electronic systems. Its wide range of inductance values makes it suitable for applications ranging from low-power digital circuits to high-power switching circuits. Its low DC resistance along with its ferrite core makes it a high quality and reliable part, thus making it an excellent choice for high-frequency applications.
