Procurement Notes
Verify the specific manufacturer part number against official Delevan documentation to confirm electrical ratings and mechanical footprint. Ensure compatibility with surface mount assembly processes. Check for RoHS compliance status and lead-free specifications relevant to your manufacturing requirements before finalizing procurement.
Selection Notes
Select this component when a 47 µH common mode inductance is required for high-frequency noise attenuation. Consider the 2 A current rating and low DC resistance for power integrity. Evaluate the 7.24 mm square footprint against available board real estate. Confirm thermal performance meets operational temperature ranges during circuit design.
Part Context
This component belongs to the CM6149R series of common mode chokes manufactured by Delevan (API Delevan). The series offers various inductance values within a standardized low-profile surface mount package. These components are engineered for consistent performance in filtering applications across industrial and consumer electronics sectors.
Replacement Considerations
Consult official Delevan cross-reference lists or distributor substitution tools for verified equivalent parts. Ensure replacement components match the 47 µH inductance, 2 A current rating, and 7.24 mm x 7.24 mm footprint. Verify that alternative sources maintain identical electrical characteristics and mounting specifications.
