Procurement Notes

Verify the specific suffix (e.g., MLC) against official Coilcraft documentation to confirm exact electrical tolerances and packaging specifications. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the selected variant matches the required impedance and current ratings for the target circuit design before finalizing procurement.

Selection Notes

Select this component when a low-profile 0805 footprint is required for USB 2.0 interfaces. The 500 mA current rating suits typical peripheral connections. Verify that the 322 nH inductance and 670 Ohm impedance at 100 MHz align with the system's EMI requirements and signal integrity needs.

Part Context

This part belongs to the 0805USB series from Coilcraft, which offers various inductance values for different speed standards. The 0805USB-672MLC represents a mid-range inductance option within this family, balancing size constraints with necessary filtering performance for digital signal lines.

Replacement Considerations

Consult official Coilcraft cross-reference guides for verified substitutes. Ensure any replacement maintains the 0805 footprint, 500 mA current rating, and compatible impedance characteristics.
