Common Mode Chokes Procurement Notes

This component is officially discontinued as per the CMT Series Product Change Notice dated January 4, 2016. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer production. Confirm the specific suffix 'R' matches the required reel or bulk packaging configuration if sourcing from distributors. Ensure the lead time and authenticity are validated against official Eaton documentation before procurement.

Common Mode Chokes Selection Notes

Select this part only if the design accommodates its physical dimensions and through-hole pin configuration. Verify that the 3.2 mH inductance value meets the specific frequency requirements at 10 kHz. Ensure the circuit current does not exceed the 4.4 A rating to maintain performance. Consider the vertical mounting orientation during layout planning.

Common Mode Chokes Part Context

The CMT2-7-R belongs to the CMT series of common mode chokes from Eaton Electronics Division. This series was designed for general-purpose power line filtering applications. The component represents a standard through-hole solution for electromagnetic interference reduction in electronic circuits prior to its discontinuation.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers must evaluate alternative components based on matching electrical parameters such as inductance, current rating, and DCR, while ensuring mechanical compatibility.
