• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific suffix designation against manufacturer documentation to confirm packaging configuration, such as reel or cut tape options. Ensure that the selected variant matches the required inductance and current ratings for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component based on its 25 µH inductance value and 3 A current handling capability. Consider the 0.01 ohm DC resistance for power loss calculations. Confirm compatibility with automated surface mount assembly processes due to the SMD package style and specified thermal operating limits.

Part Context

This part belongs to the CM6149R series of common mode chokes manufactured by Delevan. The series offers various inductance values tailored for different filtering requirements while maintaining consistent physical dimensions and mounting characteristics across the product line.

Replacement Considerations

Cross-reference with other CM6149R series variants for alternative inductance values. Verify pinout and dimensional compatibility when substituting with components from other manufacturers offering similar surface-mount common mode choke specifications.
