Procurement Notes
Verify the specific ordering suffix to ensure correct packaging configuration, such as cut tape or reel quantities. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the selected variant matches the required impedance and current ratings for the target circuit design.
Selection Notes
Select this component when designing circuits requiring low inductance for high-frequency signal integrity alongside common mode noise reduction. The 120 Ohm impedance at 100 MHz makes it suitable for USB and other high-speed interfaces. Consider the 450 mA current rating to ensure adequate headroom for the application's operational requirements.
Part Context
This part belongs to the WE-CNSW series of SMD common mode line filters by Würth Elektronik. These components are engineered for signal line applications where minimal insertion loss is critical. The series provides various impedance options to match different frequency attenuation requirements while maintaining a small physical profile.
Replacement Considerations
Check for direct substitutes within the WE-CNSW series that offer similar impedance characteristics. Verify pin compatibility and thermal performance if replacing with components from other manufacturers. Ensure any alternative meets the same AEC-Q200 qualification if used in automotive contexts.
