LI0805H400R-10

Chip Ferrite Bead Overview

The LI0805H400R-10 is a single-line ferrite bead from the Laird-Signal Integrity Products LI series, designed for EMI filtering in power and signal lines. It features a 0805 (2012 Metric) surface-mount package with dimensions of 0.079 inches long by 0.049 inches wide and a maximum height of 0.043 inches (1.10mm). The component provides an impedance of 40 Ohms at 100 MHz, supports a rated current of 1A, and has a maximum DC resistance (DCR) of 150 milliohms. It operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression for high-frequency noise on power and signal traces.
• Monolithic construction ensures reliable performance in compact surface-mount layouts.
• Low DC resistance minimizes voltage drop and power loss in the circuit path.

Chip Ferrite Bead Applications

• Power supply line filtering
• Signal line noise suppression
• High-speed digital circuit protection

Chip Ferrite Bead Procurement Notes

Verify the suffix '10' against legacy variants like '-00', as suffixes may indicate packaging or compliance differences without altering electrical function. Confirm RoHS status and lead times directly with the manufacturer or authorized distributors, as availability for this specific suffix should be validated prior to order placement.

Chip Ferrite Bead Selection Notes

Select this component when a 40 Ohm impedance at 100 MHz is required for noise attenuation. Ensure the 1A current rating meets the application's peak and continuous load requirements. The 0805 footprint allows for space-constrained designs while maintaining compatibility with standard SMT assembly processes.
