• Compact 0805 footprint suitable for dense PCB layouts

Chip Ferrite Bead Applications

• Power supply output filtering
• Signal line EMI suppression
• High-current circuit protection

Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number against official Laird documentation to ensure accuracy. Confirm that the 0805 package size and 4A current rating align with your design requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure storage conditions are maintained to preserve component integrity before assembly.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required alongside effective high-frequency noise attenuation. The 31 Ohm impedance at 100 MHz offers moderate filtering for broadband noise. The 4A current handling capability makes it suitable for main power rails where lower current beads would saturate or overheat.

Chip Ferrite Bead Part Context

This component belongs to the HI series of high-current ferrite beads from Laird-Signal Integrity Products. The series is characterized by its ability to handle significant current loads while maintaining effective EMI suppression in a standard surface-mount form factor. It complements other series like MI and LF which target different current and impedance profiles.
