Common Mode Chokes (CMC) are electronic components used to reduce the amount of electromagnetic interference (EMI) in a system. The CM6149R-473 is a type of Common Mode Choke (CMC) designed for use in high-voltage applications. The choke is designed to reduce common-mode noise produced by high voltage and current sources, such as TV antenna lines, DC power lines, and other electrical systems operating at high voltage levels. It is also designed to withstand extremely high temperatures and withstand high mechanical vibration.

The CM6149R-473 is an ultra-high-temperature, Ultra Common Mode Choke (UCMC). This type of Common Mode Choke is designed for use in environments where the temperature or other environmental conditions may be extreme, such as in an automotive application. The UCMC design permits the choke to maintain a high level of performance in high temperature applications, while still providing exceptional EMI suppression.

The working principle of the CM6149R-473 is based on the principle of EMI reduction by differential mode and common mode currents. The CM6149R-473 is designed to reduce common-mode noise (CMN) by allowing differential mode currents to flow through it, while simultaneously blocking common mode currents. The blocking of the common mode currents by the CM6149R-473 helps reduce EMI emission from the system, thus improving system performance.

The CM6149R-473 is commonly used in TV antenna lines, DC power lines, and other high-voltage systems with high EMI requirement applications. It is designed to meet the stringent requirements for automotive EMI suppression as well as high-voltage and EMI requirements for medical and other regulatory standards. The CM6149R-473 is also designed to reduce EMI in harsh industrial environments.

In addition to reducing EMI, the CM6149R-473 can also serve other functions in high-voltage applications. For example, it can provide noise cancellation, direct current (DC) isolation for equipment, radio-frequency interference (RFI) filtering, and voltage spikes suppression. The CM6149R-473 can also be used for high-speed applications such as Ethernet, Fiber, USB, or other high-bandwidth connections.

In summary, the CM6149R-473 is a common mode choke designed for high voltage applications. It is designed to reduce common-mode noise (CMN) by allowing differential mode currents to flow through it, while simultaneously blocking common mode currents. The CM6149R-473 is also often used for other purposes such as providing noise cancellation, DC isolation, RFI filtering, and voltage spikes suppression in high-voltage and industrial applications.
