Common Mode Chokes, also known as Coman Mode Filters and Line Filters, are a form of passive electronic component used for filtering out conducted noise (or electromagnetic interference – EMI) in power or signal circuits. This noise, which is typically of a differential (or noise) voltage or current, is removed via induction that results from the magnetic field developed within the core winding structure of the Common Mode Choke. Common Mode Chokes usually take the form of inductors with two or more parallel windings, each having a symmetrical magnetic path through the core, as well as having the same number of turns.

The TCM0403S-350-2P is a Common Mode Choke consisting of a ferrite core wound with two parallel metallic windings. The core material is an amorphous ferrite with a high permeability allowing much higher inductance than air or powdered iron cores. The windings consist of an aluminum-coated copper wire, with an identical number of turns, allowing it to provide a high degree of EMC suppression. Due to the double-winding structure and their construction, the chokes offer high resistance against C-field, E-field and D-field influences.

One of the major application fields for the TCM0403S-350-2P is in commercial environments where there is a need to filter out both radiated and conducted electromagnetic interference. It can be used in the protection of sensitive electronic devices such as computers and other electronic components. It is also suitable for applications in the industrial and military field, as well as in automotive electronics.

TCM0403S-350-2P\'s working principle is based on the fact that the core has a low reluctance, allowing the magnetic flux to circulate within the windings of the choke. As the current flows through the winding, a magnetic field is generated, inducing voltages in the other winding. These induced voltages oppose the noise voltages, resulting in a decrease in the noise due to a cancellation effect. The Common Mode Choke also has a reverse current suppression capability due to the presence of a diode connected in series with each winding.

In conclusion, the TCM0403S-350-2P Common Mode Choke is an effective solution for reducing conducted EMI, as well as improving safety in electronic systems. It is suitable for a wide variety of applications and is able to provide good EMC suppression performance. Additionally, due to its double-winding structure and its construction, it also offers high resistance against C-field, E-field and D-field influences.
