Fixed Inductors

Fixed Inductors are one of the most commonly used electrical components in a wide variety of applications. They are used in everything from consumer electronics to defense and aerospace, and are used in all types of switching and filtering applications. In this article, we will take a look at the application field and working principle of the IMS05WDEV220K40 Fixed Inductor.

Application Field

The IMS05WDEV220K40 Fixed Inductor is a high current, high frequency SMD power inductor, designed for high efficiency, high power density applications. It is designed to handle up to 4.7A DC current with a low core loss. Its internal construction has a ferrite core, and insulated copper coil.It is ideal for use in applications such as laptop power systems, digital displays, set top boxes, printers and other electronic appliances. The inductor is also often used in the power supplies of industrial equipment, such as motor controllers, plant automation and data communication systems.

Working Principle

The IMS05WDEV220K40 Fixed Inductor works on the principle of electromagnetic induction. In this process, an electrical current passing through a coil of wire will generate a magnetic field which in turn induces a voltage in the coil. This is the principle behind the operation of transformers, generators and motors.The IMS05WDEV220K40 Fixed Inductor consists of a ferrite core wound with several turns of insulated copper wire. The resulting inductor is then enclosed in an epoxy resin to protect it from moisture.When an alternating current is applied to the coil, the varying magnetic field induces an electromotive force (EMF) across the coil. This EMF in turn oscillates at the same frequency as the applied current. The EMF is proportional to the rate of change of the magnetic flux around the coil.The applied current passing through the windings of the inductor will create a constant, opposing magnetic field which will cause the EMF induced in the coil to be dissipated. The end result is a reduction in the current passing through the coil, which is referred to as inductance.

Conclusion

The IMS05WDEV220K40 Fixed Inductor is just one of many types of Fixed Inductors available on the market. It is a high current, high frequency SMD power inductor, designed for high efficiency, high power density applications. It works on the principle of electromagnetic induction, where an electrical current passing through a coil of wire generates a magnetic flux which in turn induces a voltage in the coil. The end result is a reduction in current passing through the coil, which is referred to as inductance. It is ideal for use in applications such as laptop power systems, digital displays, set top boxes, printers and other electronic appliances.
