Fixed inductors are electronic components that store electric energy in an electromagnetic field, commonly mistaken for resistors. The IHSM7832ER391L is a type of fixed inductor that features a small size, low profile, and high rated current capabilities. It is particularly suitable for applications such as on-board power systems, personal computers, and other electrical circuits.

The IHSM7832ER391L is constructed from a core made of Mag-Fab magnetic powder silicon steel with a cylindrical bobbin made of UL 94V-EX4 polyphenylene sulfide. It has a marked inductance of 33 μH and can handle up to 1,200 mA of rated current. Additionally, the inductor features a maximum DC resistance of 0.126 ohms and a rated saturation current of 1,000 mA.

The working principle of the IHSM7832ER391L is fairly simple. When an AC voltage is applied across the terminals of the inductor, an electromotive force is created that builds an electric flux in the core. This then generates a current through the entire winding. This current stores energy in the magnetic field, which is then released back into the coil when the voltage is switched off. This process is repeated each cycle, which is why it is also known as a “reactive component.”

As a fixed inductor, the IHSM7832ER391L has numerous applications. It is used in power supplies, inverters, EMI filters, buck converters, isolators, switch mode power supplies, and other such devices. It is also used in the design of high-frequency circuits, custom transformers, and voltage regulation circuits. Additionally, this type of inductor can be used in the design of DC-DC converters, power factor correction circuits, and motor control circuits.

The small size and high current capabilities of the IHSM7832ER391L make it highly suitable for a variety of applications. Its ability to store electrical energy in an electromagnetic field makes it an ideal choice for use in electronic circuits and other high-frequency applications. This type of fixed inductor is also robust enough to withstand short-circuits, surges, and other electrical shocks, making it a reliable choice for industrial and commercial applications.
