Common Mode Chokes

Common mode chokes (CMCs) are components that are used to mitigate electromagnetic interference (EMI) in electrical systems. CMCs are primarily used in applications involving the transmission of data over signal paths where EMI must be controlled in order to prevent damage or degradation of the signal. Below is an overview of the CMT-8110, a common mode choke designed for EMI attenuation in both balanced and unbalanced signal lines.

Applications of the CMT-8110

The CMT-8110 is a common mode choke designed to provide wideband EMI suppression for balanced and unbalanced signal lines with a frequency range of up to 10MHz. The CMT-8110 is also suitable for use in a variety of applications, including power line filters, audio systems, computer systems, electrical instrumentation, switching power supplies, and more. Additionally, the CMT-8110 is RoHS compliant and UL listed, so it can be used in any commercial application.

Working Principle of the CMT-8110

The CMT-8110 is an inductor-based common mode choke that uses a ferrite core to achieve wideband EMI suppression. The choke consists of a toroidal ferrite core with an outer winding and an inner winding. The outer winding is connected to ground, while the inner winding is connected to the signal lines. When an EMI source in the form of a common mode current is applied, its response is attenuated by the CMT-8110 choke. The choke works by providing a low impedance path to the common mode current, which causes it to be dissipated in the form of heat rather than propagating through the signal line.

Conclusion

The CMT-8110 is a widely used common mode choke designed for EMI attenuation in both balanced and unbalanced signal lines. The CMT-8110 is suitable for use in a variety of applications, including data transmission, power line filters, audio systems, computer systems, and more. The working principle of the CMT-8110 is based on an inductor-based ferrite core with an outer winding and an inner winding. When an EMI source in the form of a common mode current is applied, the CMT-8110 provides a low impedance path to it, which causes it to be dissipated in the form of heat.
