Applications
- Signal line protection in electronic circuits
- EMI filtering for high-speed data interfaces
- Power supply input noise reduction
Procurement Notes
Verify the specific suffix or packaging designation (e.g., reel vs. bulk) against the manufacturer's official documentation before ordering. Confirm that the required operating temperature range and current ratings align with the system design requirements. Ensure compatibility with standard SMT assembly processes given the component's surface-mount configuration.
Selection Notes
Select this component when a compact footprint is required alongside moderate inductance values for common mode interference mitigation. Evaluate the 750 mA current rating to ensure it exceeds the peak operational currents of the target application without saturation. Consider the low DC resistance to minimize insertion loss in sensitive signal paths.
Part Context
This part belongs to the CM6149R series of unshielded common mode chokes manufactured by API Delevan. The series is characterized by its low-profile surface-mount package suitable for automated placement. It serves as a passive electromagnetic interference filter component within the broader category of inductors and coils.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-referencing requires matching inductance, current rating, and physical dimensions to ensure functional interchangeability without redesigning the PCB layout.
