Fixed inductors are electrical components primarily used to store and control energy in an electrical circuit. The IM04SHR47G is one such component that can be used for a variety of applications. This article will provide an overview of its working principle and field of applications.

Overview

The IM04SHR47G is an axial inductor with a through-hole mounting type. It has an inductance of 4.7 μH ±20%, a working frequency of 1MHz, and a rated current of 1.21A. This inductor is designed with a ferrite core material and has a temperature rise of 85°C.

Working Principle

The primary function of an inductor is to store energy in a magnetic field created by a coil of wire. In a circuit, the alternating current flowing through the inductor will induce a varying magnetic field which, in turn, produces a varying magnetic flux. This varying magnetic flux creates a “back emf” which opposes the incoming current flow and, consequently, causes the current to be reduced. In other words, inductors act as a filter, limiting the amount of AC current that passes through an electrical circuit.

Applications

One of the primary applications of the IM04SHR47G is in power-line noise filters. Due to its high inductance rating, this inductor can be used to filter the line noise to reduce EMI interference. Additionally, the IM04SHR47G is well-suited for switching regulators, as its inductance can help regulate the flow of current. This helps ensure that the voltage is constant and the current is not too high. Finally, this inductor can also be used in radio-frequency circuits, as its high inductance rating helps to prevent any unwanted signals from being transmitted.

Conclusion

The IM04SHR47G is a through-hole mounted axial inductor with a ferrite core and an inductance rating of 4.7 μH ±20%. It has a wide range of applications, including power-line noise filters, switching regulators, and radio-frequency circuits. This inductor exhibits great EMI suppression due to its high inductance rating, thus making it a valuable component in any electrical circuit.
