CMS1-7-R Description

Short technical summary and product information.

The CMS1-7-R is a two-line common mode choke from Eaton - Electronics Division, designed for power line noise filtering. It provides 41.5 µH inductance per line at 100 kHz and is rated for 2.6 A current, making it suitable for low-current power supply applications.

 

The component features a maximum DC resistance of 19 mΩ (typ), helping to minimize power loss. It operates over a wide temperature range from -40°C to 160°C, supporting use in demanding environments.

 

The choke is supplied in a horizontal 4-pad surface mount package measuring 9.40 mm x 7.20 mm with a maximum height of 2.60 mm, allowing compact placement on printed circuit boards. The two-line configuration provides common mode filtering for power lines.

 

The device is designated RoHS3 compliant and meets MSL Level 1 requirements for moisture sensitivity.
