LI0805H151R-00

Chip Ferrite Bead Overview

The LI0805H151R-00 is a single-line ferrite bead chip from the Laird LI series, designed for EMI filtering in power and signal lines. It features a 0805 (2012 metric) surface-mount package with dimensions of 2.00mm x 1.25mm x 1.10mm max height. The component provides an impedance of 150 Ohms at 100 MHz and supports a maximum current rating of 800mA. Its DC resistance is limited to 150 milliohms, and it operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression for sensitive circuits
• Designed for integration into compact surface-mount layouts
• Supports high-current applications with low DC resistance

Chip Ferrite Bead Applications

• Power line filtering
• Signal line noise reduction

Chip Ferrite Bead Procurement Notes

Verify component status as this part is obsolete and no longer manufactured. Confirm availability of direct substitutes such as the LI0805H151R-10 variant. Check RoHS compliance requirements, as this specific suffix may not meet current environmental standards compared to active replacements. Ensure design files are updated to reflect the substitute part number before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component only if legacy compatibility is required or for non-critical prototyping where obsolescence does not impact long-term supply. For new designs, prioritize active alternatives like the LI0805H151R-10 which offer similar electrical characteristics but ensure ongoing manufacturing support. Evaluate thermal performance and current handling capabilities against circuit demands.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the LI series of EMI filtering components manufactured by Laird-Signal Integrity Products. These chips are engineered to attenuate high-frequency noise while maintaining signal integrity in dense electronic assemblies. The 0805 footprint allows for standard automated placement processes in modern PCB manufacturing workflows.

Chip Ferrite Bead Replacement Considerations

The LI0805H151R-10 is a confirmed direct substitute. Verify pinout compatibility and impedance curves when transitioning from the obsolete -00 suffix to the active -10 variant.
