Common mode chokes are widely used in many applications. They are designed to block the high frequency signals while allowing the low frequency signals to pass. PE-0403MCMC900ST is one such common mode choke that can be used to filter out high frequency interference, reduce noise interference, and suppress ground loop.

The PE-0403MCMC900ST common mode choke is a surface mounted filter with a rated current of 900mAmps and an impedance of 68Ohms during the normal operation. The device contains a core and two windings around, in order to utilize the coupled magnetic field that is generated by the windings for filtering.

The principle of the PE-0403MCMC900ST is that, it filters out part of the high frequency interference signals on the signals or power line. The common mode choke can effectively block the common mode current, while still passing the differential mode current. It acts like a low-pass filter, which allows the low frequency signals to pass and blocks the high frequency signals, thus reducing external interference. This is especially beneficial in applications of signal lines, where more stability and accuracy of the signal is needed.

The PE-0403MCMC900ST is capable of suppressing common mode noise, such as radio frequency interference (RFI). This is done by isolating the power or signal line common mode signals and converting these signals into parasitic interference signals. Then, the device creates a magnetic field around the power line or signal line which stops the RFI signals and reduces the noises coming from external sources.

The PE-0403MCMC900ST can also be used in ground loop applications. It can be connected between two ground lines and create a flux around them that nullifies the external loop current. This is beneficial in suppression or isolation of ground loop applications, such as between a chassis and a ground point, or between the power supply input and the ground.

The PE-0403MCMC900ST has many applications, such as in common mode noise suppression, ground loop prevention, and signal line filtering. It is a very effective device that can reduce the noise interference on power lines, signal lines and in chassis grounding. The device also has a rated current of 900mAmps and an impedance of 68Ohms during the normal operation, thus making it an ideal choice for many applications.
