Fixed Inductors

Fixed inductors, also known as chokes, are components designed to provide an inductance in circuits. The 5522-RC is a type of fixed inductor that provides a solution for minimizing radiated noise from switching and power supplies. It also has excellent blocking capabilities.

Application Field

The 5522-RC is designed to be used in power and control lines in a wide range of electronics. For instance, in switching power supplies, the components of the 5522-RC are used to suppress noise. In addition, they can also improve the stability of the current in control lines. In audio applications, the 5522-RC can be used to filter out audible noise such as humming and buzzing. The component can also be used to improve the quality of low-end frequency signals, providing a better overall sound.

Working Principle

The 5522-RC is a fixed inductor with a radial design. It is composed of an air-core inductor and two radiating plates. By operating in a slightly modified inductor configuration, the 5522-RC is able to maintain an equivalent Q value of greater than 4.5 for frequencies ranging from 10kHz to 1MHz.

As current passes through the inductor, the air-core creates a magnetic field. This magnetic field induces a voltage in the two radiating plates, which in turn reduces the inductor’s size. This reduces the amount of noise that the inductor produces by reducing the number of spiral turns that are present in the air-core.

The 5522-RC also features a built-in EMI shield that helps to further reduce radiated noise. This shield works by absorbing the electromagnetic radiation from the inductor and thus shielding the circuit from noise. In addition, the EMI shield also provides additional protection against mechanical damage caused by vibration and shock.

Conclusion

The 5522-RC is a fixed inductor that offers a solution for reducing radiated noise in power and control lines. Its radial design helps minimize the size of the inductor while its built-in EMI shield provides additional protection against electromagnetic interference. The component has a wide range of applications, and can be used in switching power supplies, audio systems, and more.
