Chip Ferrite Bead Procurement Notes

Verify component availability status as the LI0805H400R-00 is listed as discontinued by the manufacturer. Confirm end-of-life timelines and potential obsolescence risks before finalizing design implementations. Ensure that any replacement strategies account for long-term supply chain stability and compatibility with existing board layouts.

Chip Ferrite Bead Selection Notes

Select this component when a 40 Ohm impedance at 100 MHz is required for 0805 footprint constraints. Consider the 800mA current rating and 150 milliohm DCR limits against circuit requirements. Evaluate thermal management capabilities within the specified -40°C to 125°C operating range for the intended application environment.
