Common Mode Chokes Procurement Notes

Verify the exact part number suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the 2.7A current rating and 750 µH inductance meet the specific circuit requirements. Check for any RoHS or REACH compliance documentation if required by your manufacturing standards. Ensure the horizontal package style fits within the designated PCB footprint constraints.

Common Mode Chokes Selection Notes

Select this component when a shielded common mode choke with high current handling is needed for surface mount applications. The 35 mOhm DCR indicates low power loss characteristics suitable for efficient power paths. Consider the 0.300-inch height limit to ensure compatibility with enclosure clearances. The 750 µH value provides effective attenuation for specific frequency ranges typical in EMI filtering scenarios.

Common Mode Chokes Part Context

This component belongs to the CMF64 series of common mode chokes from Gowanda Electronics. The series offers various inductance values and current ratings tailored for different power and signal integrity needs. The CMF64 designation typically refers to the specific case size and mounting style, ensuring consistency across similar products in the lineup.

Common Mode Chokes Replacement Considerations

Direct substitutes must match the 750 µH inductance, 2.7A current rating, and 35 mOhm DCR. Verify that alternative components share the same horizontal surface mount package dimensions and pinout configuration. Cross-reference with Gowanda's official equivalent lists for guaranteed compatibility.
