Procurement Notes

Verify obsolescence status before design finalization, as this component is marked as discontinued. Confirm availability through secondary distributors or authorized surplus channels if immediate procurement is required. Ensure RoHS compliance documentation aligns with specific project requirements, noting that some sources indicate limited RoHS information availability. Validate package compatibility during the sourcing phase.

Selection Notes

Select this component only if the 01005 footprint is mandatory for the layout constraints. Compare the 75-ohm impedance specification against target noise frequencies to ensure effective attenuation. Evaluate the 260 mA current rating against peak load conditions to prevent saturation. Consider alternative active parts if supply chain stability is critical due to the obsolete lifecycle status.

Part Context

This ferrite bead belongs to the BK series of multilayer chip bead inductors. The series is engineered for suppressing electromagnetic interference in high-speed digital circuits. The 01005 package size represents one of the smallest form factors available for this component type, enabling miniaturization in space-constrained designs such as mobile phones and wearable devices.
