Procurement Notes
Verify the specific suffix (MLC vs MLB) against the Bill of Materials, as packaging or tolerance variations may exist. Confirm current availability status directly with authorized distributors, as supply constraints are noted for this series. Ensure the selected variant matches the required impedance and current ratings for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring effective common mode rejection for USB 2.0 signals. The low DC resistance minimizes voltage drop across the data lines. Verify that the 161nH inductance value aligns with the specific frequency requirements of the application to ensure adequate noise attenuation without distorting the signal integrity.
Part Context
This part belongs to the 1206USB series from Coilcraft, which specializes in common mode chokes for high-speed digital interfaces. The series provides solutions for maintaining signal integrity in environments prone to electromagnetic interference. These components are engineered to meet stringent EMC requirements for modern electronic devices utilizing high-speed serial communication protocols.
Replacement Considerations
The 1206USB-172MLC is a documented alternative within the same series offering similar functionality. Verify compatibility regarding inductance values and physical dimensions before substitution.
