Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number against official Laird documentation to ensure authenticity. Confirm that the specific suffix matches the required impedance and tolerance specifications. Check RoHS compliance status directly from the datasheet. Ensure the ordering quantity aligns with available packaging formats such as cut tape or reel. Validate the component's suitability for the intended thermal environment before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0402 footprint for EMI suppression. Choose based on the 47 Ohm impedance requirement at 100 MHz for target noise frequencies. Ensure the circuit current does not exceed the 300 mA rating to prevent saturation. Verify compatibility with standard surface-mount assembly processes. Consider the low DC resistance to minimize voltage drop in sensitive power paths.

Chip Ferrite Bead Part Context

This component belongs to the LI series of ferrite beads from Laird-Signal Integrity Products. The series offers various impedance values and package sizes for different filtering needs. The LI0402C470R-10 specifically addresses applications requiring moderate noise attenuation in small form factors.
