LI1806E101R-10

Chip Ferrite Bead Overview

The LI1806E101R-10 is a single-line ferrite bead chip manufactured by Laird-Signal Integrity Products. It features an 1806 (4516 metric) surface-mount package with dimensions of 4.50mm length and 1.60mm width. The component provides an impedance of 100 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 500mA and has a maximum DC resistance (DCR) of 300 milliohms. The device operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference filtering for power and signal lines
• Monolithic construction designed for surface-mount assembly
• Rated for high-temperature operation up to 125°C

Chip Ferrite Bead Applications

• Power line noise suppression
• Signal line EMI filtering
• High-frequency circuit protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix '10' against official datasheets to confirm compliance status, as suffixes may indicate RoHS or REACH variations. Confirm the manufacturer source directly from Laird-Signal Integrity Products documentation rather than relying solely on distributor descriptions. Ensure the part number matches the exact impedance and current ratings required for the design.

Chip Ferrite Bead Selection Notes

Select this component when a 100 Ohm impedance at 100 MHz is required for 1806 footprint designs. The 500mA current rating suits moderate power applications. Compare DCR values against thermal constraints. Verify availability status as older variants may be obsolete while newer suffixes remain active.

Chip Ferrite Bead Part Context

This component belongs to the LI series of EMI filtering and RF inductors produced by Laird-Signal Integrity Products. The series offers various impedance values and package sizes for different filtering requirements. The LI1806E101R-10 specifically targets applications needing moderate current handling in a standard 1806 case size.

Chip Ferrite Bead Replacement Considerations

Direct replacement options include other Laird parts with identical electrical characteristics but updated suffixes if the original is discontinued. Cross-manufacturer substitutes like Murata BLM series should be evaluated for impedance tolerance and current rating compatibility.
