2643167751

Overview

Fair-Rite 2643167751 is a split ferrite cable core designed for electromagnetic interference suppression. It utilizes Material 43 and provides an impedance of 115 ohms at 100 MHz. The component features a clip-together design with dimensions of 65.28 mm width and 0.033 inch height. It has an internal diameter of 2.57 inches, allowing it to accommodate large cables. The unit operates within a temperature range of -20°C to +125°C and complies with RoHS standards.

Feature Summary

• Split construction allows installation around existing cables without disconnection
• Clip-together mechanism ensures secure assembly and retention
• Material 43 composition optimized for high-frequency noise attenuation

Applications

• Suppression of conducted EMI on power and signal cables
• Noise reduction in computer and laptop peripheral wiring
• Electromagnetic compatibility enhancement in cellular device cabling

Procurement Notes

Verify the specific impedance value against your schematic requirements, as sources indicate variations between 115 and 169 ohms. Confirm that the 2.57-inch internal diameter matches your cable bundle size. Ensure the clip-together style is compatible with your assembly process. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this part when retrofitting ferrite suppression onto large-diameter cables where solid cores cannot be installed. Material 43 is suitable for frequencies above 10 MHz. Compare the 115-ohm impedance against other series options like 2643167851 if higher impedance is needed. Consider the physical bulk of the 65 mm width when planning enclosure space.

Part Context

This component belongs to Fair-Rite's 26 series of free-hanging ferrite cores. These are distinct from snap-on rings or multi-aperture toroids. The 26 series focuses on split-core designs for easy integration into existing harnesses. Material 43 is a standard choice for broadband noise suppression in digital electronics.

Replacement Considerations

The 2643167851 is a similar split core but offers 169 ohms impedance. Verify if the lower 115-ohm impedance of the 2643167751 meets your specific filtering needs. No direct pin-compatible substitutes exist due to the unique split geometry.
