RN152-1-02

Common Mode Chokes (CMCs) are used in numerous applications, such as noise suppression, EMI/RFI attenuation, and power line filtering. In recent years, RN152-1-02 CMCs have become increasingly popular thanks to their high performance and ease of integration into both old and new applications. This article will discuss the RN152-1-02 application field as well as the working principle behind CMCs.

RN152-1-02 Application Field

RN152-1-02 is a common mode choke for both AC mains and DC power lines. It is a cost-effective solution for noise suppression. In addition to EMI/RFI attenuation, RN152-1-02 is suitable for transportation and communication systems, consumer devices, audio/visual equipment, and medical equipment. Furthermore, RN152-1-02 can be used for energy management and voltage control.

Working Principle of Common Mode Chokes

Common Mode Chokes are passive electronic components that suppress or attenuate Common Mode Noise (CMN) on AC power and DC power lines. This is accomplished by applying a magnetic field to the CMN. Common Mode Chokes work by creating a voltage difference between two points, thus reducing the CMN. Since the CMN is induced current, the magnetic field created by the Common Mode Choke reduces the amount of current, thus reducing the noise.

The structure of Common Mode Chokes consists of a series of windings on a core. The core is composed of multiple materials - usually ferrite, core iron, and a combination of other ferromagnetic materials. The number of windings on the core will determine the amount of suppression. The windings interact with the CMN, creating a magnetic field that restricts the flow of current.

Types of Common Mode Chokes

Common Mode Chokes come in a variety of shapes and sizes. Generally, they can be classified into three types: linear CMCs, toroidal CMCs, and wound-rods CMCs. Linear CMCs are composed of a single coil, while toroidal CMCs are composed of two or more coils. Wound-rods CMCs are composed of multiple coils, usually arranged vertically.

Conclusion

RN152-1-02 CMCs are a cost-effective solution for noise suppression and EMI/RFI attenuation. The device works by creating a magnetic field using its windings, which in turn reduces CMN. Common Mode Chokes come in a variety of shapes, sizes, and types, making them suitable for a wide range of applications.
