Procurement Notes
Verify the specific suffix 'MLC' against official Coilcraft documentation to confirm packaging and tolerance specifications. Confirm availability status as supply conditions may vary by region and distributor. Ensure compatibility with PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component when filtering common mode noise is required for differential high-speed signals. Verify that the 0.5 A current rating meets circuit requirements. Check impedance characteristics at target frequencies to ensure effective noise suppression without signal degradation.
Part Context
This part belongs to the 1206USB series from Coilcraft, specialized for USB 2.0 and other high-speed digital interfaces. The series provides compact solutions for EMI suppression in space-constrained designs while maintaining signal integrity for protocols like HDMI and FireWire.
Replacement Considerations
Consult official Coilcraft documentation for verified substitute part numbers within the 1206USB series or equivalent product lines. Do not assume interchangeability based on package size alone; electrical parameters must match exactly.
