Procurement Notes
Verify the specific impedance value and current rating against the latest official datasheet before integration. Confirm that the package dimensions and footprint match the target PCB layout requirements. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when designing circuits requiring common mode rejection for differential signaling standards such as USB 2.0 or FireWire. Consider the 1.2 A current capacity and low DC resistance for power efficiency in data lines. Evaluate the unshielded construction against potential electromagnetic interference constraints in the system environment.
Part Context
This component belongs to the BWCU series of SMD common mode chokes from Pulse Electronics. These devices are engineered to suppress electromagnetic interference in digital communication interfaces. The series offers various impedance values and current ratings to suit different high-speed data transmission protocols.
Replacement Considerations
Check for direct substitutes within the same BWCU series or equivalent offerings from other manufacturers that match the 67 Ohm impedance at 100 MHz and 1.2 A current rating. Verify pin compatibility and mechanical dimensions to ensure seamless replacement without PCB redesign.
