Chip Ferrite Bead Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm if the updated suffix variant or alternative manufacturer components are suitable replacements for your design requirements. Ensure compatibility with existing PCB footprints and thermal management strategies when transitioning from discontinued inventory.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring compact, multi-channel ferrite filtering in space-constrained designs. Consider the 300mA current rating and 200mOhm DCR limits to ensure adequate performance without excessive voltage drop. Evaluate the 1206 array form factor against single-line alternatives for density requirements.

Chip Ferrite Bead Part Context

This component belongs to the DA series of ferrite bead arrays from Laird-Signal Integrity Products. It is specifically engineered for high-density circuit boards where multiple signal lines require simultaneous noise attenuation. The 1206 package size allows for standard surface-mount assembly processes while providing significant filtering capability in a small area.
