Common Mode Chokes Procurement Notes

Verify RoHS compliance status directly with the manufacturer or authorized distributor prior to procurement, as exemption details may vary. Confirm lead time requirements for surface mount components to ensure alignment with production schedules. Validate terminal plating specifications against soldering process compatibility to prevent assembly defects during reflow or wave soldering operations.

Common Mode Chokes Selection Notes

Select this component when a 1.8 mH inductance value is required for common mode noise attenuation at 10 kHz frequencies. Ensure the circuit design accommodates the 1.4 A current rating without exceeding thermal limits defined by the 106 mOhm DC resistance. Verify that the horizontal footprint dimensions fit within the available PCB real estate constraints.

Common Mode Chokes Part Context

This part belongs to the CMF64 series of standard common mode inductors from Gowanda Electronics. The series offers various inductance values tailored for surface mount applications. The CMF64-1804SM specifically addresses mid-range inductance needs within this product family, providing a balance between noise suppression capability and current handling capacity for general electronic systems.

Common Mode Chokes Replacement Considerations

Cross-reference with other CMF64 series variants such as CMF64-5004SM or CMF64-7504SM if different inductance values are acceptable. Verify pinout compatibility and physical footprint consistency before substituting to ensure seamless integration into existing board layouts without redesign.
