Procurement Notes
Verify the specific datasheet version and RoHS/REACH compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the AEC-Q200 qualification meets the specific requirements of your target application environment. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel, as specified in the official product documentation.
Selection Notes
Select this component when a compact 0805 footprint is required for common mode noise suppression in data lines. The 67 Ohm impedance at 100 MHz makes it suitable for high-frequency interference mitigation. Ensure the circuit current does not exceed the 400 mA rating to maintain performance and reliability under operating conditions.
Part Context
This part belongs to the WE-CNSW SMD series of common mode chokes manufactured by Würth Elektronik. These components are designed for surface mount technology and utilize ferrite core materials. The series is engineered to provide effective noise filtering in space-constrained electronic designs while maintaining signal integrity.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified substitute part numbers within the WE-CNSW family. Cross-reference impedance, current ratings, and package dimensions to ensure compatibility.
