LI0402B800R-10

Chip Ferrite Bead Overview

The LI0402B800R-10 is a single-line ferrite chip bead from the Laird Signal Integrity Products LI series, designed for surface mount assembly in the 0402 (1005 metric) package. It provides an impedance of 80 ohms at a test frequency of 100 MHz and supports a maximum DC current rating of 200 mA. The component features a maximum DC resistance (DCR) of 800 milliohms and operates within a temperature range of -40°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference filtering for power and signal lines
• Compact 0402 surface mount footprint for space-constrained designs
• High-frequency attenuation characteristics centered at 100 MHz

Chip Ferrite Bead Applications

• Power line filtering in portable electronic devices
• Signal integrity management in high-speed digital circuits
• EMI suppression in compact consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer datasheet for final electrical tolerances and RoHS compliance status before integration. Confirm that the 0402 package dimensions align with your PCB land pattern requirements. Ensure the 200 mA current rating meets the operational load conditions of your target circuit to prevent saturation or excessive heating during continuous use.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile 0402 ferrite bead is required for 100 MHz noise suppression. The 800 mOhm DCR ensures minimal voltage drop for low-current applications up to 200 mA. Consider the LI series characteristics for general-purpose EMI filtering where standard impedance profiles are sufficient for the specific signal line being protected.

Chip Ferrite Bead Part Context

This part belongs to the Laird Signal Integrity Products LI series, which focuses on ferrite beads for power and signal line filtering. The series offers various impedance values and current ratings across different package sizes, allowing designers to select components that balance size constraints with specific filtering performance needs for modern electronic assemblies.

Chip Ferrite Bead Replacement Considerations

Direct substitutes within the same LI series may be available if impedance or current ratings differ. Verify package compatibility and thermal characteristics when considering alternative manufacturers. Cross-referencing with other 0402 ferrite beads requires matching the 80 Ohm @ 100 MHz specification and 200 mA current limit.
