Fixed Inductors

Inductors are one of the more basic kinds of components in any electrical system. They are used in combination with other components to create electrical circuits that are used for a variety of purposes. The IDC2512ER681M is an example of a fixed inductor, and its application field and working principle is the subject of this article.

Application Field

The IDC2512ER681M is a fixed inductor with an inductance of 6,8µH (6,8 uH) and 8.0A saturation current. This type of inductor is typically used in DC and AC switching and waveform signal transmission, as well as conducted interference suppression. An example of this would be using the IDC2512ER681M in conjunction with a low pass filter circuit, which is used to reduce high frequency noise. This type of inductor is also suitable for applications such as switching-mode power supply (SMPS), limiting inrush current, and electromagnetic compatibility (EMC).

Working Principle

An inductor works by creating an electromagnetic field that opposes the flow of current. The electric field acts as a brake to the flow of the current, slowing it down and storing energy in the form of a magnetic field. The amount of opposition to the current depends on the inductance, which is the measure of the resistance of an inductor to changes in current. In the case of a fixed inductor such as the IDC2512ER681M, the inductance is predetermined and cannot be changed.

The IDC2512ER681M also has a saturation current, which is the maximum amount of current that the inductor can handle before it begins to saturate. Saturation occurs when the magnetic field generated by the inductor is so strong that it opposes the flow of the current. Exceeding the saturation current can cause the inductor to overheat and malfunction.

Conclusion

The IDC2512ER681M is a fixed inductor with an inductance of 6,8µH (6,8 uH) and 8.0A saturation current. It is typically used in DC and AC switching and waveform signal transmission, as well as conducted interference suppression. It is also suitable for applications such as switching-mode power supply (SMPS), limiting inrush current, and electromagnetic compatibility (EMC). It works by creating an electromagnetic field that opposes the flow of current, and has a predetermined inductance as well as a saturation current.
