Fixed inductors are electrical components whose inductance value is fixed. They are widely used in electronic circuits to filter out certain frequencies and to store energy. The SCMD4D12C-220 is a fixed inductor, and its application field and working principle will be explored in this article.

Application Field

The SCMD4D12C-220 fixed inductor can be used in a variety of applications. Its 220μH inductance value is ideal for filtering out common-mode signals in commercial/industrial/instrumentation AC-DC power supplies. The maximum DC current is 4.9A and the maximum DC resistance is 0.14Ω, making it suitable for high-power applications. In addition, it can also be used in other AC and DC power converters.

Working Principle

The operation of a fixed inductor is based on the principle of electromagnetic induction. An alternating current passing through the inductor will create an electromagnetic field around the coil. This field will create a secondary current that will oppose the original current. This opposition to the current flow causes the inductor to resist the flow of current and store energy.

In addition to its role of filtering out specific frequencies, the inductor is also used to store energy. The energy is stored in the inductor\'s magnetic field, which is created by the current passing through it. By using a capacitor in conjunction with the inductor, it can be used in resonant converters for power conversion.

Conclusion

The SCMD4D12C-220 fixed inductor is a versatile device that can be used in many applications, including power supplies and converters. Its 220μH inductance value and resistance to current flow make it an ideal choice for high-power applications, such as commercial/industrial/instrumentation AC-DC power supplies. It works by utilizing the principle of electromagnetic induction, creating an electromagnetic field that resists the flow of current and stores energy. The inductor can be combined with a capacitor to create a resonant converter for power conversion.
