2643002404

Overview

Fair-Rite Products Corp. part number 2643002404 is a solid round ferrite cable core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, which provides high magnetic permeability suitable for broadband applications in the 25 MHz to 300 MHz frequency range. The component features a Parylene coating for environmental protection and corrosion resistance. It is classified as a shield bead with a solid design, intended for free-hanging installation on cables.

Feature Summary

• Solid round construction made from Material 43 ferrite
• Parylene coating for enhanced durability and moisture resistance
• Broadband performance characteristics across 25-300 MHz

Applications

• Electromagnetic interference suppression on cables
• Shield bead applications for signal integrity
• Broadband frequency noise reduction

Procurement Notes

Verify the specific impedance value at 100 MHz against the official datasheet, as distributor listings may lack this precise parameter. Confirm that the Parylene coating specification matches project requirements for chemical and thermal resistance. Ensure the physical dimensions align with available cable clearance before ordering.

Selection Notes

Select this component when Material 43 properties are required for high-frequency noise attenuation. The Parylene coating distinguishes it from standard uncoated variants, offering superior protection in harsh environments. Consider the solid round geometry for easy sliding onto existing cable assemblies without disassembly.

Part Context

This part belongs to the Fair-Rite 26 series of ferrite cable cores. The 26 series typically includes various shapes and sizes optimized for different cable diameters and impedance requirements. Material 43 is a common choice for general-purpose EMI suppression in the VHF and UHF bands.

Replacement Considerations

Check Fair-Rite's cross-reference guide for equivalent shield beads with similar inner diameter constraints. Verify if uncoated versions (e.g., 264300xxxx) meet environmental needs if cost is a factor. Ensure substitute parts maintain the same Material 43 composition for consistent impedance profiles.
