Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement. Confirm that the AEC-Q200 certification aligns with your specific project requirements. Ensure the selected packaging format matches your automated assembly capabilities.
Selection Notes
Select this component when designing circuits requiring robust common mode rejection for differential signaling applications. The 1.3 µH inductance value is suitable for filtering lower frequency noise while maintaining signal integrity. Consider the 1 A current rating to ensure adequate headroom for operational loads without saturation.
Part Context
This part belongs to the WE-CNSW series, which specializes in surface-mount common mode chokes. These components are engineered to meet the stringent reliability and performance demands of modern electronic systems, particularly within the automotive sector where space constraints and environmental durability are critical design factors.
Replacement Considerations
Consult official Wurth Elektronik documentation for verified cross-reference part numbers. Do not substitute with generic equivalents without validating impedance curves and thermal characteristics against the original specifications.
