Thanks to the fully automated process, a high degree of winding symmetry and constantly high quality can be achieved.

Common and Differential Mode Behavior

common mode component

When the common mode component of a signal tries to pass through the choke, it encounters a high impedance. This is caused by the magnetization of the core and the resulting mutual inductance in the coil.

differential mode

In contrast to the common mode behavior, the differential mode signal will see almost no impedance, which can be explained by the magnetic field compensation in the core. If the core is not magnetized, there is no mutual inductance so that the useful signal can pass through.

Common Mode Choke for Controler Area Network (CAN)

Common mode chokes are essential components in CAN bus systems, providing several important benefits that enhance the performance and reliability of the network. Here are some key aspects of their use:

1. Noise Suppression

2. Improving Signal Integrity

3. Reducing Emissions

4. Enhancing Immunity

Common mode chokes are vital for maintaining the performance and reliability of CAN bus systems. Their proper implementation ensures robust communication in your system.

The partnumber 784234101 is approved for CAN-Applications
