CM7560-824

Common Mode Chokes

The CM7560-824 is a common mode choke specifically designed for EMI/EMC filtering operations. It works to reduce interference and electrical noise on two conductors, typically found in the data transmission line, by canceling the common mode signal. This product operates in the frequency range of 0 to 100 MHz and provides an insertion loss of up to 40dB. It features an uncompressed bandwidth that is suitable for most all applications, as well as an embedded transformer with a rated impedance of 600ohm.

Application Field

The CM7560-824 has a wide variety of applications, from automotive and medical to industrial and consumer. It can be used in the control of EMI/EMC emissions on data transmission lines in order to facilitate communication and ensure reliable operation of electronic devices. In automotive applications, the choke is used to protect the ECUs and other electronic modules from EMI-induced malfunctions. The CM7560-824 also finds use in medical applications, primarily for controlling EMI around MRI, X-ray and ultrasound machines.

Working Principle

The working principle of the CM7560-824 revolves around the fact that the device is composed of two inductors in series. As a result, the common mode signal is cancelled out at the signal\'s frequency. The inductors are designed to provide maximum suppression while not compromising on insertion loss, so the device can be used without fear of signal degradation. The inductors also serve to provide a high amount of protection from EMI interference, as they make it difficult for undesired electrical noise to pass through the circuit.

The main function of the CM7560-824 is to reduce the level of common mode noise along the low-frequency signal line it is connected to. This allows for a more consistent and reliable transmission of data. The choke also works to reduce EMI emissions, providing increased protection to the associated components and shielding the sensitive equipment it is connected to. The choke is made up of two interconnected windings, each of which has its own magnetic field that interacts with the current passing through them, which ultimately leads to the noise cancellation.

Conclusion

The CM7560-824 is a specialized common mode choke designed specifically for EMI/EMC filtering operations. It works to reduce interference and electrical noise on two conductors, primarily found in data transmission lines, by effectively canceling the common mode signal. The device has a wide range of applications, from automotive and medical to industrial and consumer applications. Its main function is to reduce the level of common mode noise along the low-frequency signal line, allowing for a more consistent and reliable transmission of data.
