IMCH1812ER221K

Fixed inductors refer to inductors in which the inductance does not change. The IMCH1812ER221K is a fixed inductor characterized by a ferrite-core-based structure. As a commonly used inductor, its application field is wide and its working principle is simple.

The application of the IMCH1812ER221K includes power supplies, inverters, converters and measurement circuits. In power supplies, the inductor helps generate high-voltage output. In inverters, the inductor delivers output power to a circuit. In conversion circuits, the inductor acts as a resonance unit to achieve high peak current and voltage. In measurement circuits, the inductor is used in conjunction with other components to measure electrical parameters.

As for its working principle, the IMCH1812ER221K, like all inductors, materials, such as ferrite, are wrapped around a single coil and then a magnetic field is generated within the core. When there is an AC current passing through the coil, an inductance will be generated which will resist any change of the current. The purpose of the inductor is to allow the current to stay constant and prevent the surge current. In addition, when the inductor is connected to a load, it will store the energy in the form of a magnetic field and then gradually release it when the voltage decreases.

In summary, IMCH1812ER221K is a fixed inductor with a ferrite-core based structure. It has a wide range of applications, such as power supplies, inverters, conversion circuits and measurement circuits. Its working principle is to generate a magnetic field within the core by wrapping a single coil with ferrite core and then resist any change of current. Moreover, it is also able to store and gradually release the energy when the voltage decreases.
