Common Mode Chokes Procurement Notes

Verify the specific suffix designation when ordering, as variants such as CMF23H-153191-B indicate bulk packaging. Confirm that the required inductance tolerance and current ratings align with the design specifications. Ensure the horizontal mounting style and radial lead configuration fit the target PCB layout constraints before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when a 15 mH inductance value is required for common mode noise reduction. The 1.9 A current rating suits applications with moderate power levels. Consider the physical footprint of 26.5 mm by 24.8 mm for space planning. The wide operating temperature range allows use in varied environmental conditions without derating concerns.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF series of common mode chokes. It shares the same physical housing and mounting characteristics with other models in the CMF23H family, differing primarily in inductance values and current handling capabilities. The series provides standardized form factors for consistent mechanical integration across various designs.

Common Mode Chokes Replacement Considerations

Direct substitutes include CMF23H-153191-B, which shares identical electrical parameters but differs in packaging format. Other CMF23H series components may serve as functional replacements if their inductance and current ratings meet or exceed the requirements of the original design.
