Fixed inductors are essential components of all electrical and electronic circuits. They are usually made of an insulated metallic core wrapped with an inductive winding of copper or other conductive material. The CIG21F2R2MNC is a fixed inductor that combines a ferrite core and a high-conductivity copper winding. It is particularly suited for use as a high-frequency noise filter in a wide variety of applications.

The CIG21F2R2MNC inductor features a low DC resistance rating of 21 Ohms, a high inductance rating of 2 mH and a wide operating temperature range of -40°C to +85°C. This combination of characteristics makes it a great choice for high-frequency noise suppression applications, such as filtering out unwanted content in audio signals or attenuating electromechanical interference in power supplies.

At the core of this inductor is a ferrite core. This type of core is composed of metal oxide particles, typically iron oxide, and is usually formed by sintering powdered components. Its high magnetic permeability enables the CIG21F2R2MNC to store a very large amount of magnetic energy in a small space, allowing it to act as an effective filter for high-frequency noise. The copper winding of the inductor plays a key role in this process by enabling efficient transmission of the inductive energy across the component.

When power is applied to the inductor, the copper winding carries an electrical current that generates a magnetic field that is concentrated in the ferrite core. As this field accumulates in the core, it drives the electric current back to the winding, forming a self-resonance loop. This loop serves to trap the high-frequency noise in the inductor, greatly reducing it in the rest of the circuit.

The CIG21F2R2MNC fixed inductor is ideal for use in a variety of applications where high-frequency noise needs to be filtered out. Such applications include radio receivers, cars, LCD monitors, digital devices, and power supplies.

At its heart, the CIG21F2R2MNC fixed inductor is a simple component that offers reliable performance in high-frequency noise suppression applications. The combination of a ferrite core and copper winding, along with its low DC resistance and wide operating temperature range, make this inductor a great choice for any application that requires effective high-frequency noise filtration.
