Common Mode Chokes Procurement Notes

Verify the specific suffix requirements against official Triad Magnetics documentation before ordering. Confirm that the through-hole footprint matches your PCB design constraints. Ensure the 9.3 A current rating meets your circuit's peak load demands. Check for any specific packaging variations associated with the -B designation.

Common Mode Chokes Selection Notes

Select this component when high current capacity and significant inductance are required for common mode noise attenuation. The 1500 V AC rating makes it suitable for mains-connected applications. Compare its physical dimensions and thermal characteristics against space-constrained alternatives to ensure compatibility with the final assembly.

Common Mode Chokes Part Context

This part belongs to the Triad Magnetics CMT series of common mode chokes. These components are widely used in power electronics to mitigate conducted emissions. The CMT-8118-B specifically addresses applications requiring higher current ratings compared to lower-inductance variants within the same family.

Common Mode Chokes Replacement Considerations

Consult Triad Magnetics datasheets for direct equivalents. Verify that substitute parts match the 7.3 mH inductance, 9.3 A current rating, and 1500 V AC voltage specifications. Ensure mechanical compatibility for through-hole mounting.
