Procurement Notes
Verify the specific suffix 'T' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact electrical requirements for the target USB 2.0 application before procurement.
Selection Notes
Select this component when shielded common mode chokes are required for USB 2.0 interfaces. Compare impedance characteristics and current ratings with similar models in the SCM20 series to ensure compatibility with the specific circuit design constraints.
Part Context
This component belongs to the SCM20 series of surface mount common mode chokes from Allied Components International. The series includes variants such as SCM20-121M-RC, which share similar form factors but may differ in electrical parameters or packaging options.
Replacement Considerations
Cross-reference tools indicate parametrically similar parts from manufacturers like Coilcraft, including the 0805USB-902MLB and 1206USB-113MLC series, which serve as potential substitutes for USB 2.0 common mode filtering.
