IMC2220ER822J Fixed Inductors

Fixed inductors are simple physical components that store energy in a form known as an electromotive force (EMF) by generating a magnetic field. This is done by establishing a current flow from one terminal to another. The IMC2220ER822J is a physically large, rectangularly-shaped, fixed inductor that is able to store more energy than many other inductors on the market due to its size.The IMC2220ER822J fixed inductor is an ideal choice for applications which require a high current handling capacity for relatively low losses such as buck converter circuits, flyback transformers, and other types of switch-mode power supplies (SMPS). It is able to operate at a maximum temperature of +150 degrees Celsius and a maximum current of up to 880 amperes. Additionally, this inductor has a magnetic core material that offers excellent noise suppression properties.In order to understand how a fixed inductor works, it is important to review its basic working principle. The primary source of the stored energy is the flow of an electric current through a coil, which has a correspondingly magnetic field. As the coil has a certain impedance, the field interacts with the coil to set up an opposing force within the coil causing an increase in its inductance. The magnitude of this increase is the basis of how much power is stored. For this specific inductor, its inductance is specified as 0.22mH.The inductance value of the IMC2220ER822J is further increased due to the unique properties of its magnetic core material. The core material ensures that the magnetic flux that forms inside and outside the coil is kept localized and concentrated, which has an impact on how much power is stored. This concentrated magnetic field is also what helps reduce the amount of electrical noise produced by the inductors. In addition to its physical size, the IMC2220ER822J benefit from a long service life due to the use of a high temperature 105 OCC (Organic Coating) insulating material. This insulating material is applied over the copper wire to ensure that the insulation levels remain secure for longer time even under high-temperature conditions. The IMC2220ER822J fixed inductor is truly a remarkable component, offering a larger range of features and higher power handling capabilities than many other inductors. Its working principle as well as the unique properties of its magnetic core allows it to store more energy than many other inductors. Furthermore, the use of a high temperature insulation material makes it suitable for use in a variety of high temperature applications. Whether for buck converters, flyback transformers, or for other high-current applications, the IMC2220ER822J fixed inductor is an ideal choice.
