Overview
The BWCU00322518161M00 is a surface-mount common mode choke manufactured by Pulse Electronics. It features a two-line configuration with an impedance of 160 Ohms at 100 MHz and a maximum DC current rating of 680 mA. The component has a maximum DC resistance of 120 mOhms and operates within a temperature range of -40°C to +105°C. Its physical dimensions are 3.2 mm in length, 2.5 mm in width, and 1.8 mm in height.
Feature Summary
- Designed for USB 2.0, IEEE1394b, and LVDS applications
- Surface mount PCB installation style
- Unshielded construction
Applications
- USB 2.0 interfaces
- IEEE1394b connections
- LVDS signal lines
Procurement Notes
Verify the specific impedance value against official datasheets, as conflicting public data lists either 90 Ohms or 160 Ohms. Confirm the maximum DC current rating of 680 mA versus alternative listings of 370 mA. Ensure the package height matches the required 1.8 mm specification before finalizing procurement orders.
Selection Notes
Select this component for high-speed digital interfaces requiring common mode noise suppression. The 3.2 x 2.5 mm footprint suits compact designs. Verify thermal performance at the specified 680 mA limit. Ensure compatibility with automated SMT assembly processes given the surface mount package type.
Part Context
This part belongs to the BWCU series of common mode chokes from Pulse Electronics. It is categorized under RF Inductors and Chokes. The series is specifically engineered for protecting data lines in consumer electronics and computing devices against electromagnetic interference.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, current rating, and physical dimensions.
