Fixed inductors are a type of electronic component that is designed to provide inductance to an electric circuit. In particular, they are designed to generate a constant flow of current at a predetermined frequency when combined with other components. The 4922R-16L is an example of a fixed inductor, specifically designed for applications requiring high ratings and high inductance stability over a wide temperature range.

The 4922R-16L is an axial wire-wound inductor that features a robust copper-plated steel core for excellent thermal performance. This inductor is most commonly used in consumer electronics, particularly for mobile broadcasting, as well as in automotive and industrial applications. It has a nominal inductance of 16mH and a rated current of 7.4A. The temperature range is from -40°C to +105°C for both operating and storage.

The working principle of a fixed inductor is based on Faraday’s law of induction. When a changing voltage is applied across its terminals, the inductor will oppose the change in the current, storing some of the energy as an electrostatic field. This stored energy is proportional to the inductance and represents the inductance of the component. When the voltage is removed, this energy is returned to the circuit in the form of an induced current.

In the 4922R-16L inductor, the primary winding is wound around the core, and two auxiliary windings are wound in opposite directions to form the secondary windings. The primary winding is connected to the power source, and the secondary winding acts as the output. When a voltage is applied to the primary winding, the magnetic field is increased, which creates a stronger inductive coupler between the primary and secondary windings. This results in a larger induced current in the secondary winding, providing a higher output current than would be possible without the inductor present.

A fixed inductor is also used in RF (Radio Frequency) circuits, where it helps to maintain a specific frequency of operation. It accomplishes this by responding to changes in frequency by shifting the inductance frequency and amplitude accordingly. This ensures that the circuit maintains the desired frequency even in the presence of the external noise or interference, thus allowing for reliable operation.

The 4922R-16L fixed inductor offers excellent performance at a competitive price, making it an ideal choice for applications requiring high inductance stability and high current ratings. With its robust copper-plated steel core, it can provide reliable and efficient operation over an extended period of time. Its reliable performance, combined with its cost-effectiveness, make the 4922R-16L a great choice for a variety of consumer electronics, automotive, and industrial applications.
