Fixed Inductors

A fixed inductor is an electrical component that stores and releases energy in the form of a magnetic field around a coil of wire. Fixed Inductors are found in a wide variety of electrical and electronic systems, including radios, computers, power supplies and more.

4922R-40K Application Field and Working Principle

The 4922R-40K is a type of fixed inductor. It is a surface-mounted, ferrite-based component, serving as a noise suppression device capable of preventing interference and crosstalk of various components. It can also be used to reduce voltage and current spikes in power supplies.

The 4922R-40K inductor works through Faraday\'s Law of Induction, which states that when the flux linked to a conductor changes, an electromotive force (EMF) will be induced in the conductor. This is the same physics behind the generation of electricity at power plants. In the case of the 4922R-40K, this EMF is generated in the form of a magnetic field through the coil of wire.

The 4922R-40K employs a ferrite core to increase the amount of energy stored within its coil. This is because ferrite is a material with a high magnetic permeability, meaning that it is able to store a large amount of magnetic flux per unit volume. This increases the inductance of the component and thus a more powerful magnetic field is created. This increased field in turn is able to reduce the total impedance of the circuit, while also preventing interference signals from leaking in. This allows the 4922R-40K to effectively suppress noise in the circuit it is installed in.

In conclusion, the 4922R-40K is a type of fixed inductor that is able to reduce interference and crosstalk by generating a strong magnetic field through a coil of wire wrapped around a ferrite core. This is done through Faraday\'s Law of Induction, which states that when the flux linked to a conductor changes, an EMF is created in the conductor, and the ferrite material increases the amount of energy that can be stored.
