Common Mode Chokes Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape and reel or cut tape, matches production requirements. Confirm that the standard lead time aligns with project schedules, as manufacturing durations may vary based on volume and facility capacity. Ensure compliance with regional environmental regulations regarding RoHS3 and REACH status before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring robust common mode rejection for dual-line power or signal paths. The 4.4 A current rating suits moderate power applications, while the low DCR minimizes insertion loss. Consider the 160°C operating limit for environments with elevated ambient temperatures or significant self-heating from high current loads.

Common Mode Chokes Part Context

This part belongs to the CMS series of common mode chokes from Eaton Electronics Division. The series focuses on providing reliable EMI filtering solutions for surface mount technology implementations. Components in this family are engineered to meet stringent automotive and industrial reliability standards, ensuring consistent performance across diverse operational conditions.

Common Mode Chokes Replacement Considerations

Direct substitutes include the CMS3-2-R, which offers similar form factors but higher current handling capabilities. Designers should verify pin compatibility and inductance tolerances when transitioning between variants within the same product family.
