Working Principle of 41220C

The 41220C is a fixed inductor constructed with a ferrite core and two windings of coils. It uses ferrite to increase the inductance by storing energy in its magnetic field. The two windings can be connected in series and parallel circuit configurations. The inductor works by creating an artificial magnetic field which causes a current to flow through the windings in the opposite direction of the input signal. The resulting current produces a voltage called the remanence voltage that opposes the original input voltage, significantly reducing the signal amplitude.

The 41220C can provide up to 500Ω of impedance at 1MHz. Its self-resonance frequency is determined by the parameters of the core and windings. The inductance of the 41220C can be adjusted by varying the number of turns of and theproperties of the windings. Its load resistance is adjustable over a wide range, typically from 10Ω to 500Ω. This feature makes it ideal for high-speed, low-frequency applications.

The 41220C is designed with a ferrite core, which provides a high degree of magnetic permeability, allowing for the low-profile form factor common in many modern electronic circuits. The ferrite core also ensures reliable performance regardless of signal frequency or power level. In summary, the 41220C is a high-performance fixed inductor that provides reliable signal control and power management functions in a wide range of electronic circuit applications.
