Fixed Inductors

Inductors are key components in the design of analogue circuits and used primarily in power supplies. While they are invaluable in the design of stable, efficient power supplies, their use is not limited to such applications. A basic understanding of inductors is essential for anyone designing analogue circuits – from the hobbyist to the professional engineer.

IM04BH120K: Application Field and Working Principle

The IM04BH120K is an axial-lead, fixed inductor suitable for a wide range of applications, including DC-DC converters, power amplifiers, and other switching power supply circuits. It features a maximum magnetic field strength of 12mT, an inductance range of 4.7μH to 5.6μH, and a limited operating temperature range of -40°C to 85°C. The IM04BH120K is a robust and reliable component designed for operation in a wide range of applications.

A fixed inductor is an electronic component that stores energy in its magnetic field in the form of a voltage across each winding, and, when connected to an alternating current, passes an electrical current through the winding. This current creates a magnetic field around the inductor which is stored in the form of an EMF. The EMF changes in magnitude with the number of turns of the inductor\'s winding.

The application of the IM04BH120K can be found in power supplies. In a DC-DC converter, its inductor serves to store energy in the form of a voltage across each winding and convert alternating currents into a larger direct current. The another application for the IM04BH120K is in power amplifiers, where it is used to regulate the flow of the signal in order to amplify the output. In a switching power supply application, the IM04BH120K is used to boost current in order to achieve a regulated output voltage.

The IM04BH120K\'s working principle is as follows: when connected to an alternating current, the stored magnetic field in the inductor\'s windings generates an EMF across the winding which opposes the applied potential. This opposes the current that is trying to pass through the coil. The higher the number of turns of the winding, the higher the induced EMF.

The IM04BH120K is an effective fixed inductor for use in many applications. It features a maximum magnetic field strength of 12mT, has a wide operational temperature range, and can provide a current boost for applications where a regulated output voltage is required. Additionally, its operating principle consists of storing energy in the form of a voltage across each winding and producing a magnetic field to oppose the applied current.
