• Compact surface mount construction for space-constrained layouts

Applications

• USB 2.0 data lines
• IEEE 1394b (FireWire) connections
• LVDS signal paths

Procurement Notes

Verify the manufacturer designation, as documentation sources attribute this part to both Chilisin and Pulse Electronics. Confirm RoHS compliance status through official datasheets before integration. Ensure the specific suffix matches the required impedance tolerance and current rating specifications for your circuit design requirements.

Selection Notes

Select this component when designing circuits requiring common mode noise attenuation for dual differential pairs. Evaluate the 500 mA current rating against peak load requirements. Consider the unshielded nature of the device regarding electromagnetic interference susceptibility in dense board environments.

Part Context

This model belongs to the BWCU series of common mode chokes intended for portable electronics and communication interfaces. It serves as a passive filtering element to suppress electromagnetic interference on high-speed serial data buses without distorting the signal integrity of the transmitted data streams.

Replacement Considerations

Cross-reference with BWCU00252012670M3P for similar impedance characteristics but different physical dimensions. Verify compatibility with BWCU00121008900Y03 if lower current handling is acceptable.
