Fixed Inductors

Fixed inductors are electronic components used in electrical circuits to restrict the flow of electrical current to a specific level. Fixed inductors are used in circuitry to assist in the transfer of electrical energy or to help create a frequency. SD3812-220-R is a type of fixed inductor used in a variety of applications.

Application Field

The SD3812-220-R fixed inductor is typically used in high frequency converter applications. It is also used as an input filter in many systems and can be found in television and audio circuitry. Additionally, as a squirrel-cage iron core filter inductor, the SD3812-220-R can be used in electromagnetic interference suppression applications. The device also finds use in power supplies, digital systems, switching power supply applications, and many other applications.

Working Principle

Fixed inductors, like the SD3812-220-R, work by restricting the flow of electrical current in a circuit to a predetermined level. This is accomplished by the inductor when the inductor creates an effect known as self-inductance. This occurs when a current passes through the inductor, causing it to create an opposing magnetic field. This, in turn, causes a back-EMF, or voltage, that opposes the current of the circuit. Since the inductor is a fixed component, the amount of opposition remains constant. This manifests itself in the form of an output that is consistent across a wide range of frequencies.

In addition to restricting the flow of electrical current in a circuit, the fixed inductor can also be used for other purposes. By taking advantage of its self-inductive property, the inductor can be used for noise or rapid kinetic energy suppression applications. Additionally, the fixed inductor can assist in the design of non-linear circuits, such as the buck converter, and can assist in the design of resonant circuits.

Conclusion

The SD3812-220-R fixed inductor is a versatile component that can be used in a wide variety of applications. It is capable of providing stable outputs over a wide range of frequencies, making it suitable for many applications. Additionally, the inductor can be used for noise or kinetic energy suppression and can assist in the design of non-linear and resonant circuits. As such, the SD3812-220-R fixed inductor is a vital component for many electrical circuits.
