Procurement Notes
Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct impedance and tolerance specifications. Confirm that the AEC-Q200 qualification status aligns with your target application requirements. Check for any recent updates to the RoHS or REACH compliance documentation before finalizing procurement orders.
Selection Notes
Select this component when space-constrained designs require a 0603 footprint common mode choke. Ensure the 400 mA current rating meets the operational load of the protected circuit. Consider the 67 Ω impedance characteristic for effective noise suppression in high-frequency digital signaling environments.
Part Context
This part belongs to the WE-CNSA series of SMT common mode chokes. The series is designed for compact electronics requiring reliable EMI suppression. Würth Elektronik manufactures these components using advanced winding techniques to achieve consistent performance across the operating temperature range.
Replacement Considerations
Cross-reference with other WE-CNSA variants for different inductance values. Verify pin compatibility and mechanical dimensions before substituting with generic equivalents. Consult official Wurth Elektronik documentation for approved alternative part numbers.
