Procurement Notes
Verify the specific suffix and packaging configuration against the manufacturer's latest documentation before ordering. Confirm that the reel quantity matches production requirements. Ensure the voltage rating and current handling capabilities align with the target circuit design specifications to prevent performance degradation or failure under load conditions.
Selection Notes
Select this component when a low-profile SMD common mode choke is required for space-constrained designs. The 3 A current rating suits moderate power applications. Verify compatibility with reflow soldering profiles and ensure the unshielded nature does not interfere with nearby sensitive components or magnetic fields in the final assembly layout.
Part Context
This part belongs to the Delevan CM6149 series of common mode chokes. The series offers various inductance values tailored for different filtering needs while maintaining a consistent footprint. These components are manufactured by API Delevan and are categorized under passive electronic components used for electromagnetic interference mitigation in electronic circuits.
Replacement Considerations
Check for direct substitutes within the same series, such as CM6149-104 or CM6149R-683, if different inductance values are acceptable. Ensure any replacement maintains the same package dimensions and current ratings to fit existing board layouts without modification.
