Fixed inductors are components whose inductance is neither adjustable nor variable. The 4922-38L is one such example, used for electronic applications requiring a specific inductance, such as an inductor for a circuit. Common uses for these components are to suppress interference, store energy, and filter signals.

The 4922-38L is constructed of a cylindrical-shaped core either of ferrite or powdered iron. To this core, one or two wire coils are connected. The number of windings in the core is predetermined to achieve a specific inductance value, making these components non-adjustable. This is in contrast with variable inductors, which are adjustable by changing the number of turns in the core.

The working principle of the 4922-38L is based on the principles of electromagnetic induction. Electromagnetic induction is the process whereby a varying electric current induces an EMF (electromotive force) in the core. This EMF, in turn, sets up a magnetic field, adjusting in proportion to the electrical current. This is what creates the inductance, and allows this component to achieve its purpose.

The 4922-38L is usually used in radio frequency and communications circuits to suppress interference, filter signals, and store energy. It can also be used as a harmonic filter, to reject specific subjects such as spur frequencies, harmonics, and other undesired signals. In addition, it can be used as a type of delay line, to delay the electrons passing through it.

The main application field of the 4922-38L is such types of electronic circuits requiring specific inductance values, non-adjustable. As such, it can be used in filters, resonators, impedance matching circuits, and inter-stage coupling circuits. In all these cases, the use of the 4922-38L would be necessary to achieve the desired characteristics, such as selectivity, signal isolation, or power handling.

In conclusion, the 4922-38L is a fixed inductor, used in electronic applications where a specific inductance is needed. Its working principle is based on the principles of electromagnetic induction, and it is used for applications where it is necessary to suppress interference, filter signals, and store energy. Its main application field is such types of circuits requiring predefined characteristics, such as filters, resonators, impedance matching, and inter-stage coupling.
