Fixed Inductors

A fixed inductor, also known as a choke inductor, is an electrical component that stores energy in a magnetic field. It is used to resist changes in current, create an AC signal, filter frequencies, or provide delay in a circuit. The 8250-3R3K-RC is an example of a fixed inductor that serves a wide variety of applications.

8250-3R3K-RC Application Field and Working Principle

The 8250-3R3K-RC fixed inductor is a high-quality, medium-power inductor for use in high-frequency systems, such as switch-mode power supplies for mobile phones, computers, and other sensitive electronic equipment. It is also suitable for DC-DC converters and various high-frequency circuit applications. The 8250-3R3K-RC fixed inductor is constructed with a ferrite core and has a rated DC current of 3.3A, an inductance of 8.25μH, and a saturation current of 19A. The core’s high-current capability can withstand high-frequency operation without heat being generated, allowing for more efficient and reliable performance. Fixed inductors use Faraday’s law of induction to work. This law states that a changing magnetic field will induce an electric field, and this changing electric field will in turn induce a magnetic field. This interaction between the two fields creates an inductor. When a current passes through a coil, its magnetic field creates a widespread magnetic field. This magnetic field then induces a voltage across the coil. The amount of voltage induced depends on the rate of change of the current through the coil, as well as the number of turns in the coil, the size of the core, and the core material.

Conclusion

The 8250-3R3K-RC fixed inductor is an ideal choice for high-frequency systems due to its high-current rating, low temperature coefficient, and wide frequency range. Its ability to resist changes in current and provide delay in a circuit make it an ideal choice for many applications. Whether it is used in switch-mode power supplies, DC-DC converters, or other high-frequency circuit applications, the 8250-3R3K-RC is a reliable and efficient component.
