Common Mode Chokes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CMF23H-273141-B indicate bulk packaging. Confirm that the required inductance tolerance and current ratings align with the circuit design specifications. Ensure compatibility with the intended PCB footprint and mounting orientation before finalizing procurement decisions.

Common Mode Chokes Selection Notes

Select this component when a 27 mH inductance value is required for common mode noise attenuation. The 1.4 A current rating must be sufficient for the application's operational load. Consider the physical size constraints and the radial lead pitch to ensure proper fit on the target printed circuit board layout.

Common Mode Chokes Part Context

This part belongs to the CMF series of common mode chokes manufactured by Triad Magnetics. The series offers various inductance values tailored for different filtering requirements.
