Common Mode Chokes Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Gowanda Electronics or authorized distributors before procurement. Confirm that the 24 mOhm DCR specification applies to each side or single winding as noted in technical documentation. Ensure the surface mount footprint matches the design layout requirements. Check for any lead-free versus leaded variant distinctions if applicable to the specific order code suffix.

Common Mode Chokes Selection Notes

Select this component when a 500 µH common mode inductance is required in a compact surface mount form factor. Consider the 24 mOhm DCR limit for power loss calculations and the -55°C to 125°C operating range for environmental compatibility. Evaluate the 0.530-inch square footprint against available PCB real estate. Compare against other CMF64 series variants like the 220 µH or 100 µH options if different inductance values better suit the circuit design needs.

Common Mode Chokes Part Context

This part belongs to the CMF64 series of common mode chokes from Gowanda Electronics, which offers various inductance values and current ratings within the same footprint family. The series is designed for surface mount applications in aerospace, defense, medical, and industrial sectors. Gowanda provides both standard and custom magnetic components, often adhering to strict quality standards such as ISO 9001 and AS9100.

Common Mode Chokes Replacement Considerations

Direct substitutes may include other CMF64 series parts with similar inductance, such as the CMF64-5003SMLF, if lead-free compliance is specifically required. Verify mechanical dimensions and electrical characteristics against alternative manufacturers' common mode chokes before substitution.
