Feature Summary

• Provides common mode noise filtering for high-speed data lines
• Designed for compact surface-mount PCB integration
• Constructed with unshielded magnetic materials

Applications

• USB 2.0 interface protection
• IEEE 1394b (FireWire) signal conditioning
• LVDS (Low-Voltage Differential Signaling) circuits

Procurement Notes

Verify the specific manufacturer designation on official datasheets, as some sources associate this part number with Chilisin components distributed by Pulse Electronics. Confirm RoHS compliance status and exact physical dimensions against the latest engineering drawings before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring low-profile EMI suppression in differential signaling paths. Ensure the 1.3 A current rating meets the operational requirements of the target circuit. Verify that the 42 Ohm impedance value aligns with the required attenuation characteristics for the specific data rate being protected.

Part Context

This component belongs to the BWCU series of SMD common mode chokes. It is categorized under Inductors, Chokes & Coils and serves as a passive filter element. The part is distinct from power inductors or RF inductors due to its dual-line configuration designed specifically for noise reduction rather than energy storage or tuning.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, current rating, and package dimensions with equivalent products from other manufacturers.
