CM6560-105

Common Mode Chokes (CMCs) are electromagnetically-coupled high frequency filters that provide EMI suppression. The CM6560-105 is one of a wide range of commonly used high current common mode chokes designed for power line filtering. This section provides details on the application fields and working principle of the CM6560-105.

The CM6560-105 is ideal for applications where a high dB ripple rejection is needed for very low frequency mains supply filtering. The low inductance values of few mH enables the CM6560-105 to provide suppression for high current signals even at low frequencies. The key feature is the maximum operating and winding temperature which can reach 125 degree Celsius enabling reliable operation under rigorous conditions.

The CM 6560-105 is divided into two types, single and double horizontal line types. Typical applications include switching, medical, power conversion equipment, automotive systems, telecommunications, military equipment, and uninterruptible power supplies. For maximum performance, it is necessary to fit the cable and EMI filter in a common box as the power lines must be provided with an enclosing copper cover which will connect the power line to the device.

The working principle of the CM6560-105 is based on reactive components such as inductors, which are connected in series. The main purpose of a common mode choke is to reduce the noise produced by electromagnetic interference from the mains power lines. The choke will enable the mains power line to be effectively screened from any unwanted external interference.

The choke consists of two windings, one for common mode and one for differential mode, connected to the device inputs and outputs. The filter is designed to suppress any common mode noise as well as differential mode noise. The choke operates in two main ways; it limits the inductance of the mains power line, which is measured in amperes-per volt-second, allowing the signal to pass through but suppressing noise, and secondly it has a high frequency attenuation, which is measured in dB.

In addition to this, the CM6560-105 also features various integrated technologies such as automatic voltage regulation and voltage monitoring. It also includes a temperature sensor, which can help to regulate the voltage drop and maintain specified levels of voltage. The temperature sensor helps protect the device and prevents it from exceeding its rated temperature.

The CM6560-105 is designed to provide superior EMI suppression for a wide range of applications. It is suitable for power conversions and switching of medical and military equipment. The choke has been designed to reduce component size and delivered cost and to provide users with a compact yet highly reliable EMI filter with excellent performance.
