2643000201

Overview

The Fair-Rite 2643000201 is a solid cylindrical ferrite core designed for EMI suppression applications. It utilizes Material 43, providing an impedance of 31 ohms at 100 MHz. The component features a free-hanging installation type with precise dimensions: an inner diameter of 1.09 mm (0.043 inches), an outer diameter of 1.93 mm (0.076 inches), and a length of 3.81 mm (0.150 inches). This compact bead is suitable for suppressing electromagnetic interference on small gauge wires.

Feature Summary

• Constructed from Material 43 ferrite composition for effective high-frequency noise attenuation
• Solid cylindrical design allows for direct sliding onto cables without assembly hardware
• Free-hanging configuration enables flexible placement along wire harnesses

Applications

• Suppression components in electronic assemblies
• Cable and wiring noise filtering
• Board component EMI mitigation

Procurement Notes

Verify the specific ordering suffix to ensure the correct material grade and dimensional tolerance match your design requirements. Confirm RoHS compliance status if restricted substances are prohibited in your manufacturing process. Check datasheet specifications for impedance characteristics at target frequencies to validate performance suitability for your specific application environment.

Selection Notes

Select this part when a compact, non-split ferrite bead is required for small diameter conductors. Ensure the cable diameter fits within the 1.09 mm inner diameter constraint. Material 43 is appropriate for frequencies ranging from 25 MHz to 300 MHz. Verify that the solid construction meets mechanical stress requirements compared to split-core alternatives.

Part Context

This component belongs to the Fair-Rite cable ferrite product line, specifically categorized as an EMI suppression bead. It is distinct from split cores due to its solid construction, requiring installation before cable termination. The product is actively supported with technical documentation and CAD models available for integration into design workflows.

Replacement Considerations

No public confirmed substitute part numbers are identified in the provided documentation. Users should consult Fair-Rite technical support for equivalent materials or dimensional alternatives if this specific item is unavailable.
