Fixed Inductors

Fixed inductors are electrical components that store energy in the form of a magnetic field. They are frequently used in electronic circuits to provide magnetic field isolation, voltage regulation, filtering, switching, and other functions. The SCMD4D12-6R8 is a popular fixed inductor manufactured by M/A-COM and is widely used in a variety of applications.

SCMD4D12-6R8 Application Field

The SCMD4D12-6R8 fixed inductor is used in low-voltage DC-DC switching regulators, adjustable current regulators, and other electronic applications that require isolation of magnetic fields. It can also be used in phaseshift power conversion, high input impedance circuits, and EMI filtering in both commercial and industrial applications, including portable power equipment, computers, and medical equipment.

SCMD4D12-6R8 Working Principle

The SCMD4D12-6R8 fixed inductor works by creating a magnetic field when current passes through it, which has the purpose of providing reactance in an AC circuit and producing a desired voltage drop. This inductor consists of two distinct sections: the “active” section, which is the inductor coil, and the “passive” section, which is the body housing the coil.When electrical current is applied to the active section, the coil creates a magnetic field around it, which stores energy. This energy is released gradually when the current is switched off, either in the AC current or the DC. Thus, the inductor acts as a filter, allowing only certain frequencies to pass through it and blocking out others.The SCMD4D12-6R8 fixed inductor is also an EMI filter, as it can reduce the interference generated by electromagnetic fields by providing a low-impedance path for such noise. Furthermore, this inductor is designed with a very high power rating to prevent saturation of the coils, and to maintain its current carrying capacity.Finally, the inductor is also equipped with flux shielding to isolate the active portion from the passive portion and minimize the amount of noise created.

Conclusion

The SCMD4D12-6R8 fixed inductor is an ideal solution for many low-voltage applications that require isolation of magnetic fields and EMI filtering. It works by creating a magnetic field around the inductor coil when current is applied, and releasing energy gradually when the current is removed. This inductor also features a high power rating to prevent saturation, and flux shielding to isolate the active portion from the passive portion.
