Fixed Inductors

Fixed inductors are electrical components made up of a coil of wire with a core material inside of it. They use the principle of electromagnetic induction to transfer electric current from one circuit to another. The B82442H1122K000 is an inductor designed for a variety of applications, such as power supplies, filter networks, and regulators.

How Does an Inductor Work?

When a current flows through the coil of a fixed inductor, an electromagnetic field is generated. This field induces voltage in nearby electrical components, which can be useful in specific applications. The amount of induced voltage depends on the number of turns in the coil and the overall inductance. The type of core material used in the inductor also affects the voltage generated.
