Chip Ferrite Bead Procurement Notes

This component is officially discontinued and no longer in production. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer allocation. Confirm the specific suffix variant matches the required electrical specifications, as legacy stock may vary. Ensure compliance with end-of-life notifications before integrating into new designs.

Chip Ferrite Bead Selection Notes

Select this component when a 0805 footprint ferrite bead with 100 Ohm impedance at 100 MHz is required for power line applications. It is appropriate for designs needing AEC-Q200 qualified components capable of handling 2.5A continuous current. Consider the low DC resistance for minimal voltage drop in power paths. Due to discontinuation, verify long-term supply stability for maintenance or replacement cycles.
