Chip Ferrite Bead Procurement Notes

Verify part status as obsolete or end-of-life through official manufacturer channels before procurement planning. Confirm availability of alternative components if active sourcing is required. Request current documentation directly from Samsung Electro-Mechanics to ensure technical specifications match design requirements. Validate RoHS compliance status independently as public records may lack definitive confirmation.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring 120 Ohm impedance at 100 MHz on single power lines. Ensure circuit design accommodates the 2.5A current rating without saturation. Verify footprint compatibility with the specified 0805-style dimensions and 1.10mm height constraints. Consider supply chain stability given the reported obsolete status when finalizing design choices.
