Chip Ferrite Bead Procurement Notes

Verify the specific suffix designation during procurement, as it indicates compliance status. Confirm that the ordered part matches the RoHS3 requirement if environmental regulations apply to the final assembly. Ensure the supplier provides official datasheets to validate the electrical parameters against the design specifications before integration.

Chip Ferrite Bead Selection Notes

Select this component when a 1806 footprint is required for space-constrained designs needing moderate current handling. The 80 Ohm impedance at 100 MHz targets specific noise frequencies. Compare the 500 mA rating against circuit load requirements to ensure adequate margin. Consider the 300 mOhm DCR impact on voltage drop in sensitive power rails.

Chip Ferrite Bead Part Context

This part belongs to the Laird LI series of ferrite beads, which are engineered for surface-mount applications. The series offers various impedance and current ratings across different package sizes. The LI1806E800R-10 specifically addresses needs for compact, high-reliability filtering in consumer and industrial electronics where space efficiency is critical.

Chip Ferrite Bead Replacement Considerations

Direct replacement options include other Laird parts within the same series with matching impedance and current ratings. Cross-manufacturer substitutes must be evaluated for package compatibility, impedance tolerance, and thermal performance to ensure equivalent circuit behavior.
