Fixed inductors are types of electronic components that have two terminals and are used to provide inductance in an electrical circuit. In their simplest form, they are a coil of wire wrapped around a core material, usually a ferrite doughnut. Their purpose is to store energy in the form of a magnetic field when electric current passes through them. Amongst the different types of fixed inductors, the IHM2 PM4R7K is probably the most popular.

The IHM2 PM4R7K is primarily used in power electronics, such as AC/DC converters, motor controls, and power supplies. Its main advantage lies in its ability to be designed with a high current rating and withstand high temperatures. It also has a high saturation current and a low DC resistance value, making it the perfect choice for high-power applications.

The IHM inductors utilize a specially designed winding to produce a ferrite core. This core is used to store a magnetic flux field when current is passed through the inductor. The windings are encased in an epoxy mold form and also surrounded with a thin copper layer.

The IHM can handle a wide range of operating temperatures, ranging from -55 to +125°C. This capability, coupled with its low DC resistance and high current ratings, makes it the ideal choice for high-power applications. Additionally, it has a high saturation current, meaning it is capable of taking on larger surge currents with minimal drop in performance.

In terms of its working principle, the IHM2 PM4R7K inductors work by using a magnetic field to store an electrical potential energy when electric current passes through them. This energy is then free to be released back into the circuit when the current passes through an opposing magnetic field. In effect, the inductor acts as a \'capacitor\' that can store a certain amount of energy and then release it back into the system when required.

Overall, the IHM2 PM4R7K is an ideal choice for applications that require high-current ratings, as well as high-temperature capabilities. Its working principle relies on the magnetic field produced when electric current passes through it, allowing it to store and then release energy back into the circuit. With these features in mind, it is easy to see why it is one of the most popular fixed inductors on the market today.
