LI1806E101R-00

Chip Ferrite Bead Overview

The LI1806E101R-00 is a monolithic ferrite chip bead from the Laird LI series, designed for surface-mount assembly in the 1806 (4516 metric) package. It provides an impedance of 100 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current of 500 mA and features a maximum DC resistance of 300 mOhms. It operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies.

Chip Ferrite Bead Applications

• Power line filtering
• Signal line filtering

Chip Ferrite Bead Procurement Notes

Verify RoHS compliance status carefully, as datasheets indicate this specific suffix may be non-compliant compared to the -10 variant. Confirm lead times and availability directly with the manufacturer or authorized distributors, as production status can change. Ensure the ordering suffix matches the required environmental specifications for your design.

Chip Ferrite Bead Selection Notes

Select this component when a 1806 footprint is required for space-constrained designs needing 100 Ohms impedance. Compare against the LI1806E101R-10 if RoHS compliance is mandatory. Evaluate thermal performance based on the 500 mA current rating and 300 mOhm DCR to ensure adequate power handling without excessive heating.

Chip Ferrite Bead Part Context

This part belongs to the Laird Signal Integrity Products LI series of ferrite beads. These components are engineered for EMI/RFI suppression in compact electronic assemblies. The 1806 package size offers a balance between current handling capability and board space efficiency compared to smaller footprints like 0805 or 1206.

Chip Ferrite Bead Replacement Considerations

LI1806E101R-10 is a direct substitute from the same manufacturer. BLM41PG101SN1L by Murata Electronics is a similar alternative. Verify pin compatibility and impedance curves before substitution.
