Procurement Notes
Verify the specific manufacturer designation as sources indicate potential discrepancies between Pulse Electronics and Chilisin branding for this part number. Confirm RoHS compliance status and exact package type details directly with the supplier before finalizing procurement orders to ensure alignment with design requirements.
Selection Notes
Select this component when designing circuits requiring high impedance common mode rejection for low-current data interfaces. Ensure the board layout accommodates the specified SMD footprint dimensions. Verify that the 80 mA current rating meets the operational requirements of the connected USB or FireWire devices without saturation.
Part Context
This component belongs to the BWCU series of common mode chokes produced by Pulse Electronics. It serves as a passive filter element within electronic assemblies, specifically targeting electromagnetic interference mitigation in digital communication pathways. The series offers various impedance values tailored for different signal integrity standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, current rating, and physical footprint specifications from alternative manufacturers.
