Procurement Notes
Verify the specific impedance value and physical footprint against current design requirements before ordering. Confirm that the manufacturer's standard lead time aligns with project schedules. Ensure compliance with RoHS3 specifications if required by the target application environment.
Selection Notes
Select this component when a low-profile surface-mount ferrite bead is needed for single-line applications. The 37 Ohm impedance at 100 MHz suits general-purpose noise suppression. Consider the 1.6 milliohm DCR for circuits where minimal voltage drop is critical. Verify thermal stability requirements against the specified operating temperature range.
Part Context
This component belongs to Fair-Rite's series of surface-mount ferrite beads and chips. These components are engineered for integrated circuit protection and signal integrity maintenance. The product line offers various impedance values and package sizes to accommodate diverse PCB layout constraints and frequency-specific filtering needs.
Replacement Considerations
Consult official Fair-Rite documentation for verified substitute part numbers. Cross-reference impedance curves and physical dimensions to ensure functional compatibility during replacement.
