CMT2-6-R

Common Mode Chokes (CMCs) are widely used in today\'s electronic systems, especially in the telecommunications sector. CMC can effectively filter out common mode disturbances to ensure the proper operation of electronic circuits. CMCs have become an important piece of equipment in terms of providing effective EMI/EMC protection. Among many CMC designs, CMT2-6-R is one of the most popular in the market.

Application Field of CMT2-6-R

The CMT2-6-R Common Mode Choke is mainly used for signal line emission attenuation in telecommunication systems, in order to ensure the safety operation of the system and reduce harmonic interference. With its advanced design, CMT2-6-R is suitable for different working environments and provides excellent common mode differential mode noise protection.

CMT2-6-R Common Mode Choke can be applied in EMI/EMC filter application fields such as portable electronics, handsets, computers, and notebooks. It is also suitable and appropriate for indoor and outdoor telecom transmission line connections, analog or digital signal connections, data receivers and transmitters. In addition, the CMT2-6-R is widely used in automotive communication applications, such as in CAN bus networks, GSM/GPRS/CDMA networks.

Working Principle of CMT2-6-R

The CMT2-6-R Common Mode Choke consists of several windings, and its two ends are connected to each other through a set of electrical components. It works as a filter to reduce unwanted conducted and radiated EMI/EMC. The winding of the CMT2-6-R shield the signal and feedback inductance, which can prevent the flow of common-mode, differential-mode current and noise.

The CMT2-6-R can block common-mode noise and therefore attenuates interference. It has two main features: one is symmetrical structure and the other is the symmetry of the upper and lower inductance. This symmetrical design ensures high rejection performance in the low frequency range.

The CMT2-6-R also has two important working parameters: inductance and impedance. The inductance of the CMT2-6-R Choke is proportional to the number of turns, and the impedance is proportional to the wire size. The impedance and inductance should be properly selected for better EMI/EMC performance.

Conclusion

As one of the most popular Common Mode Choke, CMT2-6-R is widely used in telecommunication systems and other EMI/EMC filter application fields. Its symmetrical design and impedance/inductance values are guarantee of high rejection performance in the low frequency range, which can reduce unwanted conducted and radiated EMI/EMC noise.
