Chip Ferrite Bead Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm compliance status and functional equivalence. Confirm that the ordered component matches the required impedance and current ratings for the target application circuit. Ensure compatibility with standard reflow soldering profiles specified in the datasheet.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint is required for high-current power line filtering. The 150 Ohm impedance at 100 MHz targets common noise frequencies. Evaluate thermal performance under continuous load conditions given the 800 mA rating. Compare physical height constraints against board clearance requirements before finalizing the design.

Chip Ferrite Bead Part Context

This part belongs to the Laird LI series of ferrite beads and RF inductors. The series offers various impedance values and current ratings across multiple standard package sizes. It serves as a passive component for electromagnetic interference suppression in consumer electronics and industrial equipment.

Chip Ferrite Bead Replacement Considerations

Direct replacement options include other Laird parts within the same series with matching impedance and current ratings. Cross-manufacturer substitutes must be verified for identical package dimensions, impedance characteristics, and saturation current limits.
