Procurement Notes
Verify the specific manufacturer source when ordering, as this component originates from the Chilisin product line distributed by Pulse Electronics. Confirm that the part number suffix matches the required impedance and current ratings. Ensure the procurement channel provides original manufacturer documentation to validate authenticity and technical specifications against official datasheets.
Selection Notes
Select this component for applications requiring significant common mode attenuation at 100 MHz while maintaining low series resistance. The 850 mA current rating suits moderate power data lines. Consider the unshielded construction for cost-sensitive designs where magnetic coupling to adjacent components is manageable within the layout constraints.
Part Context
This part belongs to the BWCU series of SMD common mode chokes. It serves as a specialized EMI filter for digital communication interfaces. The series offers various impedance and current combinations tailored for different bus speeds and power requirements in portable and industrial electronics.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing footprints and electrical parameters before considering alternative manufacturers.
