LI0805G301R-00

Chip Ferrite Bead Overview

The LI0805G301R-00 is a monolithic ferrite chip bead from the Laird Signal Integrity Products 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 rating of 700 mA. The component features a maximum DC resistance of 150 mOhms and operates within a temperature range of -40°C to +125°C. This single-line filter is intended for power and signal line applications.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression on single conductors
• Monolithic construction ensures reliability in surface-mount PCB layouts
• Rated for continuous operation under specified thermal conditions

Chip Ferrite Bead Applications

• Power line filtering
• Signal line noise suppression

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation and RoHS compliance status directly with the supplier or official documentation before procurement. Confirm that the component matches the required impedance and current ratings for the target circuit design. Ensure compatibility with standard surface-mount reflow soldering profiles and check for any specific handling requirements related to the component's physical dimensions and material composition.

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 700 mA current capacity. The 0805 footprint offers a balance between size and performance. Consider the 150 mOhms DCR limit for voltage drop calculations. Verify availability as the product may be subject to obsolescence or supply constraints compared to active inventory items.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the Laird-Signal Integrity Products portfolio, which specializes in EMI filtering solutions. The LI series typically denotes specific material characteristics optimized for broadband noise absorption. As a passive component, it complements other circuit elements by attenuating high-frequency noise without affecting the DC or low-frequency signal integrity of the connected lines.
