Common Mode Chokes are devices used to suppress or eliminate electrical noise in an electrical system. They are also known as Common Mode Inductors, Common Mode Shields, or Balance Line Chokes. The primary purpose of a common mode choke is to act as a filter that blocks the transfer of RF or power line-borne noise while allowing the transfer of other signals through the choke. Common Mode Chokes have been used for decades in the telecommunications, automotive, industrial, and commercial industries.

The CM6460-125 is a common model choke specifically designed for use in high speed communication and networking applications. The CM6460-125 utilizes an internal ferrite core and is capable of handling currents up to 125 Amps. The device features an operating temperature range of -40° to 80°C and has a maximum rated inductance of 6.4Ohms. The choke design also features a 3rd harmonic suppression rating of 80%.

The CM6460-125 application field is mainly used in high speed communication system to minimize Electromagnetic Interference (EMI). It plays an important role in the filtering of EMI signals from the main path. This reduces and eliminates signal interference from the local and remote sources that can adversely impact the system performance. The CM6460-125 is specifically designed to provide EMI suppression from 150kHz to 1GHz for both local and remote sources.

The CM6460-125 working principle utilizes the principle of ferromagnetic coupling. This means that it can accept signals as input from an external source and then transfer them to an output without the need for an active rectifier or transformer. This ensures high power handling and low insertion losses while providing superior noise performance. The choke utilizes magnetic flux created by the external source to facilitate energy transfer, which creates a three-dimensional magnetic field with multiple turns on the wire. This produces an unwanted signal current which is then filtered out by the CM6460-125 common mode choke.

The device\'s performance is further enhanced by the addition of advanced Bypass Networks. This involves the addition of a capacitive network or intentional DC bias points. These act to reduce the level of EMI passing through the device while maintaining low insertion losses. The CM6460-125 also utilizes a double-layer shield in order to reduce the susceptibility of EMI entering the device.

In conclusion, the CM6460-125 is an exemplary Common Mode Choke designed to suppress EMI signals in high speed communication networks. The device utilizes the principles of ferromagnetic coupling, bypass networks, and a double-layer shield in order to provide superior noise performance and low insertion losses while maintaining impressive power handling capabilities.
