LI1806C151R-00

Chip Ferrite Bead Overview

The LI1806C151R-00 is a single-line ferrite bead from the Laird LI Series, designed for EMI filtering in power and signal circuits. It features an impedance of 150 Ohms at 100 MHz and a maximum DC resistance of 500 milliohms. The component supports a rated current of 300 mA and operates within a temperature range of -40°C to 125°C. Housed in a surface-mount 1806 (4516 Metric) package measuring 4.50mm x 1.60mm with a maximum height of 1.85mm, it is currently obsolete.

Chip Ferrite Bead Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Laird-Signal Integrity Products. Procurement must rely on secondary market distributors or verified surplus stock. Buyers should confirm lot dates and physical condition upon receipt. Direct replacement with the active LI1806C151R-10 variant is recommended to ensure long-term supply chain stability and compliance with current manufacturing standards.

Chip Ferrite Bead Selection Notes

Select this part only if legacy design compatibility requires the specific obsolete suffix. For new designs, utilize the active LI1806C151R-10 which shares identical electrical characteristics. Verify that the 300mA current rating and 150 Ohm impedance meet the target circuit requirements. Ensure the 1806 footprint aligns with existing PCB silkscreen and copper pad definitions.

Chip Ferrite Bead Part Context

Part of the Laird LI Series ferrite beads, optimized for high-frequency noise suppression. The 1806 package size balances current handling capabilities with space-constrained board real estate. Designed specifically for attenuating radio frequency interference in dense electronic assemblies.

Chip Ferrite Bead Replacement Considerations

LI1806C151R-10 is the direct active substitute. BLM41PG181SN1L is listed as a similar alternative.
