Chip Ferrite Bead Procurement Notes

This component is officially obsolete and no longer manufactured. Verification of end-of-life status is required before integration. Sourcing must rely on approved manufacturer-recommended substitutes such as BMC2AY1000AN. Confirm RoHS3 compliance and MSL level 1 availability through official channels prior to procurement planning.

Chip Ferrite Bead Selection Notes

Select this part for high-impedance noise attenuation in space-constrained designs requiring 0805 packaging. The 100mA current rating limits suitability for high-power paths. Verify thermal performance within the -55°C to 125°C operating range. Due to obsolescence, substitute selection should prioritize identical electrical parameters and mechanical dimensions.

Chip Ferrite Bead Part Context
