Chip Ferrite Bead Procurement Notes

Verify the specific manufacturer designation, as API Delevan and Delevan are associated with this part number. Confirm RoHS compliance status, as sources indicate variations regarding lead-free certification. Ensure the ordering quantity aligns with factory pack requirements, typically 3000 units per reel. Cross-reference the impedance value and package dimensions against your schematic requirements before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for noise attenuation. The 1206 footprint suits space-constrained designs. Verify that the 500 mA current rating meets the circuit's operational demands. Consider the unshielded nature of the bead for placement relative to sensitive components. Check thermal limits to ensure operation within the specified -55°C to +125°C range.
