Procurement Notes
Verify the manufacturer designation carefully, as official documentation may reference Chilisin or Pulse Electronics interchangeably for this specific part number. Confirm RoHS compliance status through the latest datasheet before integration. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by the supplier.
Selection Notes
Select this component when designing circuits requiring common mode noise attenuation for high-speed digital interfaces. The 160 Ohm impedance provides effective filtering without excessive signal degradation for the intended protocols. Consider the 500 mA current rating to ensure adequate headroom for the specific application's power requirements.
Part Context
This component is part of the BWCU series of common mode chokes. These devices are engineered to suppress electromagnetic interference on differential data lines. The series offers various impedance values and physical footprints to accommodate different board space constraints and filtering requirements across multiple communication standards.
Replacement Considerations
Consult official substitution lists for verified equivalents. Cross-referencing requires matching impedance, current ratings, and physical dimensions to ensure functional compatibility.
