Common Mode Chokes (CMC) are electrical components used to reduce or eliminate common mode noise on signal and power lines. CMCs work by providing an impedance to the flow of common mode currents, while allowing differential mode currents to pass with minimal impedance. The CM2718R121R-00 is a common mode choke designed with a low profile, high current rating, and excellent thermal stability. Its small size and high current rating make it suitable for a wide range of applications.The CM2718R121R-00 consists of a ferrite core wound by two separate coils. The primary function of the two coils is to provide impedance to the flow of common mode currents, while allowing differential mode currents to pass with minimal impedance. The total inductance of the CMC is determined by its total number of turns and the ferrite material used in the core. The CM2718R121R-00 has a rated inductance of 1000uH at 100kHz and a DC resistance of 0.26 ohms.The CM2718R121R-00 is designed for use in high-frequency, high-temperature applications and is particularly suited for motor drives, inverters, power supplies, and other power-electronic applications where common mode noise must be effectively reduced. It is UL recognized, RoHS compliant, and meets PFC performance requirements, making it suitable for a wide variety of applications from lighting to LED driver systems.The primary advantage of the CM2718R121R-00 is its high thermal stability. Its temperature rise is self-suppressing, and its highly effective construction ensures minimal temperature increase at the highest currents. Its low profile also means that it can be easily integrated into existing designs and takes up minimal space. The CM2718R121R-00 is available in a variety of sizes, from 8mm to 20mm, and a variety of shapes, including circular, square, and rectangular. In addition to providing common mode noise reduction, the CM2718R121R-00 is also designed to reduce differential mode noise as well. It features a double-sided construction for maximum shielding and noise reduction. This allows the CMC to pass differential mode currents of up to 20kHz with minimal impedance, while still providing effective reduction of common mode noise. The CM2718R121R-00 is also designed to minimize Eddy Current losses, making it highly efficient in a wide range of applications. Overall, the CM2718R121R-00 is an effective choice for a wide range of applications that require effective common mode noise reduction. With its low profile, high current rating, and thermal stability, the CM2718R121R-00 is an ideal solution for applications in lighting, motor drives, inverters, and power supplies, as well as for LED driver systems and other power-electronic applications.
