2643003201

Overview

Fair-Rite 2643003201 is a solid round ferrite cable core utilizing Material 43. It functions as an EMI suppression shield bead with a nominal impedance of 88 Ohms at 100 MHz, though some sources cite 105 Ohms or 110 Ohms for the same part number. The component features an inner diameter of 2.65 mm to 2.67 mm and an outer diameter of 5.33 mm to 5.6 mm. Its external length is 12.7 mm. The effective frequency range spans from 25 MHz to 300 MHz. The unit weighs approximately 870 mg.

Feature Summary

• Solid cylindrical construction designed for free-hanging installation on cables.
• Material 43 composition provides high permeability for broadband noise suppression.
• Acts as a shield bead to attenuate common mode interference signals.

Applications

• Suppression of electromagnetic interference on data and power cables.
• Noise filtering in high-frequency signal transmission lines.
• EMI mitigation in electronic equipment cabling within the 25-300 MHz range.

Procurement Notes

Verify the specific impedance value (88, 105, or 110 Ohms) required for your design against the manufacturer's current datasheet, as distributor listings show conflicting specifications for this part number. Confirm that the inner diameter tolerance accommodates the target cable size before ordering. Check RoHS compliance status directly with Fair-Rite Products Corp. to ensure adherence to environmental regulations for your region.

Selection Notes

Select this component when a solid, non-split ferrite bead is required for permanent cable treatment. Ensure the cable diameter fits within the 2.65 mm internal clearance. Material 43 is suitable for frequencies above 25 MHz; lower frequency applications may require different material compositions. Consider the physical length of 12.7 mm for spatial constraints in the assembly.

Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. It is distinct from split cores (series 61) and multi-aperture rings (series 28). The 26 series represents solid, single-piece ferrite beads intended for sliding onto cables during manufacturing or maintenance.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Alternative solutions would require sourcing components with matching Material 43 properties, similar impedance curves, and compatible physical dimensions from other manufacturers.
