Common Mode Chokes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CM9900R-335 may exist with identical electrical characteristics but different packaging or minor physical attributes. Confirm RoHS compliance status directly with the manufacturer API Delevan prior to procurement. Ensure that the required lead spacing and mounting style align with the target printed circuit board layout specifications.

Common Mode Chokes Selection Notes

Select this component when a 3.3 mH inductance value is required for common mode interference reduction in low-current data lines. The 550 mA current rating must be sufficient for the intended application's steady-state DC conditions. Consider the unshielded nature of the part regarding potential magnetic coupling with adjacent components on the assembly.

Common Mode Chokes Part Context

This component belongs to the CM9900 series of PC mount common mode chokes manufactured by API Delevan. The series offers various inductance values tailored for different filtering requirements while maintaining consistent physical dimensions and mounting styles.
