Procurement Notes
Verify the specific suffix (MLC) against official Coilcraft documentation to confirm exact electrical tolerances and packaging specifications. Confirm RoHS compliance status through the manufacturer's current datasheet. Ensure the selected variant matches the required impedance and current ratings for the target application before finalizing procurement orders.
Selection Notes
Select this component when a low-profile, single-channel solution is required for high-speed signals. Compare the 147 nH inductance and 500 mA current rating against circuit requirements. Consider the 0805 footprint constraints and operating temperature limits relative to the system environment. Verify compatibility with automated assembly processes given the SMD/SMT termination type.
Part Context
This part belongs to the 0805USB series from Coilcraft, which focuses on common mode chokes for USB and other high-speed interfaces. The series offers various inductance values to suit different frequency attenuation needs while maintaining a consistent small form factor. These components are engineered to minimize signal distortion while effectively suppressing unwanted common mode noise.
Replacement Considerations
Consult official Coilcraft substitution guides for verified alternatives. Cross-reference parameters such as inductance, DC resistance, and physical dimensions to ensure functional equivalence without modifying the PCB layout.
