Fixed inductors are passive electronic components consisting of a coil of insulated wire wrapped around a magnetic core. They are used in various electrical circuits, from simple power supplies to sophisticated electronic devices. In general, fixed inductors store energy in the form of a magnetic field and can also be used to restrict current or to couple signals between different parts of a circuit. They can also provide filtering, help with impedance matching, and can act as a step-up or step-down for other components in the circuit.

The 9220-08 is an example of a fixed inductor, and it is typically used for RF interference suppression, EMI shielding, and for providing filtering in telecom, audio, and power supply applications. Its magnetic core is constructed from ferrite, and it comes in a helical coil with copper wire for the windings. It is self-leaded and rated for up to 400mA of peak current.

The working principle of the 9220-08 is relatively simple. When current passes through the wire windings, it produces a magnetic field that is stored in the ferrite core. This stored magnetic field helps to dampen high-frequency electrical noise and to limit the peak current that can pass through the inductor. This helps to provide more reliable performance for radio frequency circuits, and it helps to keep other sensitive components from becoming damaged by overcurrent.

The 9220-08 may also be used for impedance matching, as the inductor can be used to match the impedance between two different components in the circuit. When the inductor is placed between two such components, it helps to ensure that the voltage and current levels remain balanced and that power is efficiently transferred from one component to the other. Impedance matching is important in many types of electrical circuits, as it helps to ensure that power is not wasted.

Overall, the 9220-08 is an efficient and reliable fixed inductor, and it is often used in a variety of electronic applications. Its ferrite core provides excellent magnetic storage ability, and it helps to provide filtering and impedance matching if that is necessary. Its self-leaded construction also makes it easy to install and use in a variety of different circuits.
