Fixed Inductors

Inductors are widely used in various power electronic applications. In particular, a fixed inductor is a passive component used to store energy in the form of a magnetic field in an electrical circuit. An example of a fixed inductor is the IMCH1812ER101K. This particular inductor is a low-profile fixed inductor with a shield core oriented along the x-y axes. The use of the shield core allows for better magnetic coupling efficiency and lower resistance compared to other fixed inductor designs.

IMCH1812ER101K Application Field

The IMCH1812ER101K has numerous uses in a wide range of applications. For instance, it is used in Smartphones and other mobile devices, due to its low-profile design with a shield core. Additionally, this inductor is common in power supply circuits, as well as other high-frequency switching power supplies, such as computer systems, data centers, and servers. Furthermore, it is also suitable for use in resonant inductive switching circuits.

IMCH1812ER101K Working Principle

The working principle of the IMCH1812ER101K is based on the characteristic behavior of an inductor. An inductor consists of a coil of wire wrapped around a core material. When an alternating current (AC) is introduced into the coil, it will produce a magnetic field. The intensity of the magnetic field is a function of the current passing through the coil. When an alternating voltage is applied to the coil, a time-varying magnetic field is created. This causes an induced current to flow in the coil, which in turn causes a magnetic field opposing the first one. As a result, the amplitude of the current fluctuates, thereby producing a current that is out of phase with the applied voltage. This is known as AC impedance. The IMCH1812ER101K is designed to have a low impedance over a wide range of frequencies, which makes it suitable for applications requiring low ripple current operation.

Conclusion

The IMCH1812ER101K is an ideal fixed inductor for low-profile applications. It has a wide range of uses in the fields of mobile devices, power supply circuits, high-frequency switching power supplies, and resonant inductive switching circuits. Furthermore, it has a low-impedance over a wide range of frequencies. All of these features make the IMCH1812ER101K an ideal choice for many applications.
