Applications
- Signal line filtering in electronic assemblies
- Power supply input noise suppression
- Data bus protection against common mode interference
Procurement Notes
Verify the specific packaging configuration required for production, as availability varies between bulk and reel formats. Confirm compliance requirements such as RoHS status directly with the manufacturer or authorized distributors prior to ordering. Ensure the selected variant matches the exact inductance and current rating specifications needed for the target application circuit.
Selection Notes
Select this component when a low-profile SMD common mode choke with high inductance is required. The 500 mA current rating limits suitability for high-power applications. Consider the unshielded nature of the device regarding proximity to sensitive components. Verify that the physical footprint fits the available PCB real estate constraints.
Part Context
This part belongs to the CM6149 series of common mode chokes manufactured by API Delevan. The series offers various inductance values tailored for different filtering needs while maintaining a consistent low-profile form factor. These components are engineered for surface mount technology processes.
Replacement Considerations
Cross-reference with other Delevan CM6149 variants for different inductance values. Verify mechanical compatibility with alternative manufacturers' low-profile SMD common mode chokes if supply chain adjustments are necessary.
