Common Mode Chokes are one of the most important components for power electronics, and their application areas are extremely wide. CAF-3.1-1.2 is a kind of common mode chokes, which has excellent properties and can be applied in different areas.

The structure of CAF-3.1-1.2 is relatively simple. It mainly consists of a core, a composite winding, a shell, an end ring and an external rubber body. The core is made of ferrite, and the composite winding is composed of two or three windings in the same direction. The end ring and the external rubber body are filled with epoxy resin, which makes the CAF-3.1-1.2 resistant to high temperature, humidity, dust, shock and vibration.

The working principle of CAF-3.1-1.2 is relatively simple. It works by generating an electromagnetic field at its working frequency to induce a high dc voltage, the leakage inductance of which could effectively suppress high frequency disturbances. It is also called differential mode filter, and its frequency response range is wide, which can reach up to 6GHz.

CAF-3.1-1.2 is suitable for a variety of applications. It is most commonly used in power line and communication line, which could effectively suppress surface wave and common mode interference. In audio applications, it can reduce ground loop noise and ensure the purity of signal output. It also can be used for EMI (Electromagnetic Interference) testing, which can be used to measure the radio frequency interference of electronics products. In addition, it is also widely used in the automobile industry, computer industry, and so on.

In short, CAF-3.1-1.2 is a kind of common mode choke with excellent performance and wide application range. It could effectively suppress radio frequency interference and ensure the accuracy and reliability of power supply products. With the development of electronics technology, more and more application fields of common mode chokes will be explored in the future.
