PA3747.505NL is a type of Common Mode Choke (CMC). The chokes primarily suppress differential-mode noise. This CMC features a ferrite core construction, and its two winding design is very effective at suppressing common-mode noise in a system. In addition to providing electrical noise suppression for power cables, PA3747.505NL also has advantages such as repeatable performance and good solderability.

Application Field

The PA3747.505NL Common Mode Choke is suitable for a variety of electronic devices. This includes small consumer electronics, telecommunications, medical devices, power supplies, and motor drives. Furthermore, the CMC is great for reducing noise in high-temperature applications and it stands up well to shock and vibration.

Working Principle

Common Mode Chokes work by providing inner and outer windings on a ferrite core material. As a differential noise signal passes through the choke, its noise power is suppressed or filtered out. This is because the movement of the differential noise creates a self-inductive field in the inner winding. The field generated is large enough to delete the signal differential noise while leaving any common mode noise. Due to the construction of the ferrite core, the PA3747.505NL can provide EMI filtering up to several tens of MHz.

At a more technical level, Common Mode Chokes use the magnetic material, ferrite, to store the electrical energy in the signal. As the current passes through the ferrite, it creates a self-inductive magnetic field. Essentially, the ferrite core helps the current flow stronger and smoother. So, when a differential signal passes through the choke, the magnetic field stores the electrical energy and reduces the noise in the signal.

Conclusion

The PA3747.505NL Common Mode Choke is a very effective EMI noise suppression device that can be used on a variety of electronic systems. Due to its dual winding design on a ferrite core and its repeatable performance, the PA3747.505NL can provide excellent electrical noise suppression for a variety of different applications.
