Chip Ferrite Bead Procurement Notes

Verify the manufacturer part number against official Laird-Signal Integrity Products documentation to confirm specifications. Ensure compatibility with existing board layouts regarding the 0805 package dimensions. Check for RoHS compliance status if required by specific project regulations. Confirm availability through authorized distribution channels as supply levels may vary.

Chip Ferrite Bead Selection Notes

Select this component when a 39 Ohm impedance at 100 MHz is required for power line filtering. The 4A current rating makes it suitable for higher current applications compared to standard signal line beads. Consider the 0805 package size for space-constrained designs requiring robust EMI suppression capabilities.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HI series from Laird-Signal Integrity Products, designed for broadband EMI filtering. The series offers various impedance values and current ratings in standardized packages. The HI0805P390R-10 specifically targets power line applications requiring moderate impedance and high current handling capacity.

Chip Ferrite Bead Replacement Considerations

HI0805P390R-10 is a Laird-specific designation. Equivalent components from other manufacturers must match the 0805 package, 39 Ohm @ 100 MHz impedance, 4A current rating, and 8 mOhm DCR specifications.
