The CMS1-4-R is a surface-mount common mode choke from Eaton - Electronics Division, designed for power line filtering applications. It provides 18µH inductance at 100 kHz across two lines, with a maximum current rating of 3.8A and a maximum DC resistance of 8.9mΩ.\n\nThis choke is housed in a horizontal 4-pad surface-mount package measuring 9.4mm x 7.2mm x 2.6mm. The compact design is suitable for automated PCB assembly and space-constrained layouts. It operates over a wide temperature range of -40°C to 160°C, making it suitable for demanding environments.\n\nCommon mode chokes are essential for suppressing electromagnetic interference (EMI) in power supply and signal lines. The CMS1-4-R effectively attenuates common-mode noise while allowing desired differential signals to pass. Its high current rating and low DCR help minimize power loss in high-current paths.
