Common Mode Chokes Procurement Notes

Verify the specific suffix '-B' against official documentation to confirm packaging details, as sources indicate bulk packaging but do not explicitly define quantity limits or handling requirements in the provided text. Ensure the lead time aligns with manufacturer schedules, noting that general family data suggests production cycles may vary. Confirm RoHS compliance status directly from the datasheet before procurement.

Common Mode Chokes Selection Notes

Select this component when a 47 mH inductance value is required for common mode noise attenuation at 10 kHz. The 1.1 A current rating suits applications with moderate DC load currents. Verify that the vertical package dimensions fit the available PCB real estate and that the operating temperature range meets environmental specifications.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMF series of common mode chokes. The series includes various inductance values and current ratings, such as the CMF23V and CMF23HK kits. The CMF23H variant specifically denotes the housing style and pin configuration suitable for vertical board mounting.

Common Mode Chokes Replacement Considerations

Direct substitutes include other Triad Magnetics parts within the CMF23H series with matching electrical parameters. Cross-referencing with similar inductance and current ratings from other manufacturers requires verification of physical footprint and thermal characteristics.
