Common Mode Chokes Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with design requirements. Confirm that the radial lead spacing matches the target PCB footprint. Check RoHS compliance status if required by regulatory standards. Ensure the operating temperature range aligns with the intended application environment.

Common Mode Chokes Selection Notes

Select this component when a 10.9 mH inductance value is required for common mode noise attenuation. The 3.5 A current rating suits applications with moderate power levels. The compact PCB mount form factor facilitates integration into space-constrained designs. Verify that the 122 mOhm DC resistance meets the voltage drop constraints of the circuit.

Common Mode Chokes Part Context

This part belongs to the CME series of common mode chokes from Triad Magnetics. The series offers various inductance values tailored for different filtering needs. All units share similar physical dimensions and mounting styles, allowing for standardized mechanical design across multiple product variants within the same family.

Common Mode Chokes Replacement Considerations

Cross-reference with other CME series parts like CME375-2 or CME375-6 if different inductance or current ratings are needed. Ensure any substitute maintains the same radial PCB mount style and comparable physical envelope to fit existing footprints.
