Fixed Inductors

A fixed inductor, also known as a molded inductor or a fixed-coil inductor, is a passive electrical component that is used to store and release energy in a form of electromagnetic fields. These inductors are used in various applications and are often found in radio-frequency applications, such as cellular phones, radios, and other consumer electronics. The inductor is composed of a conductor, normally a wire, wound in a coil to create an inductive reactance. A core of ferrite or other material is often included for increased inductive reactance, and the whole assembly is then encased in a mold or case. Fixed inductors are often used to filter electrical signals, to block or reduce noise, or to couple electrical circuits.

2108-H Application Field

The 2108-H fixed inductor is a small molded piece with multiple leads able to be inserted into a printed circuit board (PCB). This type of inductor is designed for high-frequency suppression in a wide range of radio-frequency communication applications, including cell phones, computers, and satellite communication, making it an ideal component for reducing interference. It is also well-suited for use in step-down or Buck-Boost switching converters.

2108-H Working Principle

The 2108-H fixed inductor works in a similar way to other types of inductors. When a current is applied to it, the inductor stores energy in the form of a magnetic field. The magnetic field, along with the inductor\'s ability to suppress high-frequency noise, cause current to be drawn away from the circuit, stopping and reducing the amount of interference. The amount of current drawn away is proportional to the inductance of the inductor; the higher the inductance, the more current will be drawn away. The overall effect of this is to filter out high-frequency noise and reduce interference.

Conclusion

The 2108-H fixed inductor is a useful and widely used component that can be found in a variety of applications. It is especially useful for radio-frequency applications, as it is able to suppress high-frequency noise and reduce interference, making it ideal for use in cell phones, radios, and other consumer electronics. Furthermore, its small size and multiple leads make it an easy component to install into a PCB, making it even more desirable. The working principle of the 2108-H fixed inductor proves extremely useful in helping to filter out high-frequency noise and reduce interference.
