Common Mode Chokes (CMT) is a type of electrical device which reduces the amount of current flowing within a system by inducing a magnetic field around the electrical interconnections. Common mode chokes are used to suppress the transmission of high frequency noise and electromagnetic interference (EMI) which can interfere with the signals in a system. The CMT1-9-R series of common mode chokes is a type of filter designed to reduce the common mode current in the wiring and transform the voltage differences across the winding to smaller values. These chokes are commonly used in a wide range of applications, including automobile engines, power supplies, household electronics, and industrial controls.

Applications of Common Mode Chokes

Common mode chokes are often used in automotive applications, dedicated power supplies, and industrial controls. Automobile engines often require a common mode choke to reduce the EMI emitted from the engine, as the fast moving parts can create a significant amount of interference. The CMT1-9-R series of chokes are often used to reduce the noise generated by the engine into the power system, which improves the performance of the engine. In situations where the power supply is dedicated to a single device, the common mode choke can help to reduce the EMI interference, which can adversely affect the performance of the device.

Common mode chokes are also used in many industrial applications, such as those involving electric motors, motor controllers, and power supplies. These chokes are used to reduce the amount of common mode noise and EMI in the system, improving system performance and reliability. Industrial control panels are often equipped with common mode chokes to reduce the levels of noise generated by the electrical components. The CMT1-9-R series of chokes is a cost effective solution for these types of applications.

Working Principle of Common Mode Chokes

Common mode chokes use electromagnetic induction to reduce the amount of current flowing between two points. An electric current flowing through a wire induces a magnetic field around the wire. Common mode chokes are designed to channel this magnetic field around the wires, in the opposite direction of the current flow. This creates a voltage differential across the choke which results in a reduction in the current flow. CMT1-9-R common mode chokes are designed to have a high impedance in the common mode, while allowing the differential mode signals to pass through without any significant reduction in signal strength.

CMT1-9-R common mode chokes can be used to effectively reduce the levels of common mode noise and EMI in a system. By channeling the magnetic field around the wires, the common mode choke impedes the current flow, reducing the amount of interference generated. The high impedance of the choke also ensures that the differential mode signals are not significantly affected, ensuring that the performance of the system is not impaired.

Conclusion

Common mode chokes are a critical component of many electrical systems. CMT1-9-R common mode chokes are designed to reduce the levels of common mode noise and EMI in a system, improving system performance and reliability. These chokes are used in a wide range of applications, from automotive engines, dedicated power supplies, and industrial control systems. By channeling the magnetic field around the wires in the opposite direction of the current flow, the common mode choke is able to reduce the current flow and reduce interference. The CMT1-9-R series of common mode chokes are a cost effective solution for these types of applications.
