Common Mode Chokes Procurement Notes

Verify the specific suffix 'SM' confirms the surface mount package variant. Confirm RoHS compliance status as standard parts may differ from LF versions. Validate that the 2.4 A rating aligns with your thermal management requirements, noting that ratings are based on specific temperature rise criteria.

Common Mode Chokes Selection Notes

Select this component when high isolation voltage is required in a compact surface mount form factor. Ensure the 1 mH inductance meets the target frequency attenuation needs. Consider the 47 mOhm DCR impact on power loss compared to lower resistance alternatives in the CMF65 series.

Common Mode Chokes Part Context

This part belongs to the CMF65 series of surface mount common mode chokes. The series offers various inductance values and current ratings. Gowanda Electronics designs these components for demanding applications requiring reliable noise suppression and high voltage isolation in space-constrained environments.

Common Mode Chokes Replacement Considerations

Check for CMF65-1003SMLF or similar series variants if different inductance or lead-free specifications are needed. Verify pinout compatibility before substituting with other manufacturers' common mode chokes.
