LI0805G301R-10

Chip Ferrite Bead Overview

The LI0805G301R-10 is a monolithic ferrite chip bead from the Laird-Signal Integrity Products LI series, designed for surface-mount assembly in the 0805 (2012 metric) package. It provides an impedance of 300 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 1 A. The component features a maximum DC resistance of 200 mOhms and operates within a temperature range of -40°C to +125°C. Physical dimensions are 2.00 mm in length, 1.25 mm in width, and a maximum height of 1.10 mm.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression on single power or signal lines
• Monolithic construction ensures reliability in surface-mount applications
• Rated for continuous operation under high DC current loads up to 1 A

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• Signal line noise suppression
• EMI filtering for high-speed digital interfaces

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'R-10' against official datasheets to confirm reel packaging specifications. Confirm RoHS compliance status as indicated in current manufacturer documentation. Ensure the selected variant matches the required impedance and current ratings for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for a single-line application with a 1 A current rating. The 0805 footprint offers a compact solution for space-constrained designs. Compare DCR values against other series variants if lower insertion loss is critical for the specific power rail.

Chip Ferrite Bead Part Context

This part belongs to the Laird MI/LI ferrite bead family, which utilizes monolithic technology for EMI suppression. The LI series typically targets general-purpose filtering needs. The LI0805G301R-10 shares the same impedance characteristics as the obsolete LI0805G301R-00, serving as its active replacement in the product portfolio.

Chip Ferrite Bead Replacement Considerations

The LI0805G301R-00 is listed as an obsolete direct substitute for this component. Verify pinout compatibility and physical dimensions before replacing legacy designs.
