Common Mode Chokes Procurement Notes

Verify the specific datasheet version and compliance certifications such as VDE, IEC, UL, and CSA before integration. Confirm that the 300 mOhm DCR and 2.9 A current rating align with your circuit's thermal and electrical constraints. Ensure the radial lead spacing matches your PCB footprint design to avoid assembly issues.

Common Mode Chokes Selection Notes

Select this component when a 36 mH inductance value is required for common mode noise reduction. It is appropriate for designs needing a 2.9 A current capacity with low series resistance. Consider its unshielded nature and physical dimensions during layout planning to ensure adequate clearance and mechanical stability on the printed circuit board.

Common Mode Chokes Part Context

The CMT-8117 belongs to the CMT series of common mode chokes manufactured by Triad Magnetics. This series focuses on providing reliable EMI suppression solutions for power electronics. The component utilizes radial leads for secure PCB mounting, distinguishing it from surface mount alternatives in the same product family.

Common Mode Chokes Replacement Considerations

Consult official Triad Magnetics documentation for verified substitute part numbers. Cross-referencing requires matching inductance, current rating, and physical dimensions to ensure functional compatibility without redesigning the host circuit.
