CMT-8109-B

Common Mode Chokes

A common mode choke (CMC) is a passive element used to suppress electromagnetic interference (EMI) by blocking common-mode noise (or current) on a power line or signal line. Common-mode chokes are used in power and data line applications, including motors and other electromechanical equipment. Common-mode chokes often use a ferrite core to guide the magnetic field produced by the input current, thereby helping to cancel or suppress the unwanted interference. Common-mode chokes can be used as part of an EMI/RFI filter, or they can be used as a standalone device.

CMT-8109-B Application Field and Working Principle

The CMT-8109-B is a Common Mode Choke specifically designed to suppress high-frequency common mode noise on DC power lines. It is designed to reduce EMI interference to sensitive circuitry connected to the same power lines. The CMT-8109-B’s ferrite core is effective in attenuating noise within a wide range of frequency. The choke is easy to mount and may be used to attenuate common-mode noise on a variety of circuits and systems.

In operation, the CMT-8109-B works by allowing a magnetic flux to be generated from the flow of current (which creates opposition to further current flow). This action reduces the signal strength of the noise, thus reducing the amount of noise on the power or signal line. As the choke reduces the intensity of the noise on the line, the performance of the connected system can be improved.

The CMT-8109-B is widely used in power supplies for computers and other electronic equipment, as well as in automotive and telecommunications applications. It is also used in EMI/RFI filters, eliminating the need for multiple passive elements. It can be used with other EM/RF components such as capacitors, resistors, and inductors, to achieve the desired EMI/RFI filtering results.

Conclusion

The CMT-8109-B is an effective and reliable Common Mode Choke designed to suppress high-frequency common mode noise on DC power lines. It can be used with other passive components to achieve the desired EMI/RFI filtering results. The power to reduce noise levels and improve circuit performance makes the CMT-8109-B an ideal choice for a variety of applications.
