Procurement Notes
Verify the specific impedance value and current rating against the official datasheet before procurement. Confirm that the package dimensions match the design footprint requirements. Ensure the operating temperature range meets the environmental specifications of the target application. Cross-reference the manufacturer part number to avoid confusion with similar series components.
Selection Notes
Select this component when a low-profile, two-line common mode choke is required for high-speed digital interfaces. The 30 Ohm impedance is suitable for specific frequency attenuation needs. Consider the 450 mA current rating to ensure it exceeds the peak current demands of the protected circuit. Verify compatibility with automated SMT assembly processes due to the small form factor.
Part Context
This component belongs to the BWCU series of compact common mode chokes from Pulse Electronics. These devices are engineered for space-constrained electronic designs requiring effective electromagnetic interference reduction. The series typically targets consumer electronics and portable devices where board real estate is limited.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult the manufacturer's official cross-reference tools or datasheets for verified alternatives.
