2743009111

Overview

Fair-Rite 2743009111 is a ferrite bead with axial leads, utilizing Material 43. It provides an impedance of 202 ohms at 100 MHz and 220 ohms at 100 MHz according to varying listings. The component is designed for electromagnetic interference suppression in electronic circuits.

Feature Summary

• Axial leaded construction for through-hole mounting
• Material 43 composition for high-frequency noise attenuation

Applications

• Electromagnetic interference suppression
• Signal line filtering

Procurement Notes

Verify the exact impedance value (202 or 220 ohms) against the manufacturer's official datasheet before procurement, as distributor listings show conflicting specifications. Confirm that the axial lead configuration matches your board layout requirements. Ensure Material 43 properties align with your target frequency range for effective noise suppression.

Selection Notes

Select this component when axial mounting is required for ferrite beads. Material 43 offers specific permeability characteristics suitable for broadband noise reduction. Compare impedance values across distributors to ensure consistency with design simulations. Verify lead length and diameter if mechanical constraints are critical.

Part Context

This part belongs to Fair-Rite's ferrite bead series, distinct from their toroidal cores like 2843010402. It serves as a discrete component for circuit-level filtering rather than a core for winding cables. The axial format differentiates it from surface-mount alternatives.

Replacement Considerations

Check equivalent axial ferrite beads from other manufacturers offering Material 43. Verify impedance tolerance and current rating compatibility. Ensure physical dimensions match existing footprints if direct replacement is needed.
