LI1806C151R-10

Chip Ferrite Bead Overview

The LI1806C151R-10 is a single-line ferrite bead from the Laird LI series, designed for EMI filtering in power and signal circuits. It features an 1806 (4516 metric) surface-mount package with dimensions of 4.50mm x 1.60mm x 1.85mm maximum height. The component provides an impedance of 150 Ohms at 100 MHz, supports a maximum DC current of 300mA, and has a maximum DC resistance of 500 milliohms. It operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression for sensitive power and signal lines
• Monolithic construction ensures reliable performance in high-density surface-mount layouts
• Optimized impedance characteristics for broadband noise attenuation

Chip Ferrite Bead Applications

• Power supply line filtering
• High-speed signal line protection
• General-purpose EMI suppression in electronic assemblies

Chip Ferrite Bead Procurement Notes

Verify the suffix '10' against the obsolete '-00' variant to ensure compliance with current RoHS standards. Confirm that the 300mA current rating meets circuit requirements. Check for lead-free availability if required by specific environmental regulations.

Chip Ferrite Bead Selection Notes

Select this component when a 150 Ohm impedance at 100 MHz is required for 1806 footprint designs. Ensure the 300mA current handling capacity aligns with the application's peak load. Consider the 500 milliohm DCR impact on voltage drop for low-voltage power rails.

Chip Ferrite Bead Part Context

This part belongs to the Laird LI series of EMI filtering components. It serves as a direct replacement for the discontinued LI1806C151R-00, offering updated material specifications while maintaining identical electrical parameters and physical dimensions for seamless integration into existing designs.

Chip Ferrite Bead Replacement Considerations

The LI1806C151R-10 is the direct successor to the LI1806C151R-00. Verify pinout compatibility and impedance curves when substituting other manufacturers' parts like Murata BLM41PG181SN1L.
