Common Mode Choke is an electrical component that helps in providing high attenuation of common mode interference frequencies while allowing desired signals to pass through. CM1011R-106 is one of the widely used common mode chokes in various applications. It is a 10-leaded common mode inductor choke, designed for high frequency interference suppression in the frequency range of 100KHz to 10MHz.

The main function of CM1011R-106 is to help reduce common mode interference caused by external electromagnetic fields or conducted noise in high-frequency equipment. This common mode choke is constructed with two independent, high permeability ferrite cores. It provides common mode noise attenuation of 30dB minimum at 10MHz and 29dB minimum at 100KHz. Due to its high attenuation and small size, this common mode choke is suitable for use in various fields including industrial, telecommunications, automotive, consumer electronics, and consumer goods.

The working principle of CM1011R-106 is based on electrical inductance. It works by winding two separate high permeability ferrite cores with several turns of wires. As signals of different frequencies pass around thes coils, an inductive impedance is created that produces a high resistance against the current. This high resistance helps to attenuate common mode interference by blocking the current from passing through the device. It is important to remember that CM1011R-106 should be placed parallel with signal lines to work properly.

In addition to its common mode noise attenuation, CM1011R-106 is also great for reducing noise currents generated by high-speed digital circuits and providing a low-resistance and high-current path for non-critical digital signals. It also has a low DCR enabling overload protection and good thermal stability. Moreover, it has excellent shielding effectiveness against higher frequency interference.

CM1011R-106 is ideal for applications such as automotive DC/DC converters, switching power supply noise suppressors, peripheral circuits, home appliance controllers, USB and Ethernet ports, digital TV, radio, and appliances. Its wide range of application makes it one of the most popular common mode chokes in the market.

To conclude, CM1011R-106 common mode choke is an essential component for providing high attenuation and interference suppression. It works by winding two separate high permeability ferrite cores and provides excellent shielding effectiveness against higher frequency interference. This makes it suitable for use in various application fields including automotive, industrial, telecommunications, consumer electronics, and consumer goods.
