2643169351

Overview

Fair-Rite 2643169351 is a solid flat ribbon cable ferrite core designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 60 Ohms at 100 MHz and 98 Ohms at 25 MHz across the 25 MHz to 300 MHz frequency range. The component features internal dimensions of 27.5 mm length by 1.1 mm height and external dimensions of 33.65 mm length by 2.64 mm height. It accommodates flat cables with widths ranging from 12.7 mm to 77 mm.

Feature Summary

• Solid split design allows installation onto existing multi-conductor flat cables without disconnecting wires.
• Material 43 composition provides effective high-frequency noise attenuation in the 25 MHz to 300 MHz spectrum.
• Free-hanging configuration enables flexible mounting orientation on cable assemblies.

Applications

• Suppression of common-mode noise on parallel data buses
• EMI reduction on flat ribbon cables in computer peripherals
• Noise filtering on internal system interconnects

Procurement Notes

Verify the specific impedance requirement against the application frequency, as datasheets list both 60 Ohms at 100 MHz and 98 Ohms at 25 MHz. Confirm that the target flat cable width falls within the 12.7 mm to 77 mm accommodation range. Ensure Material 43 characteristics align with the intended noise profile before finalizing procurement specifications.

Selection Notes

Select this component when dealing with wide flat ribbon cables requiring robust EMI suppression. The solid construction offers higher mechanical stability compared to openable cores. Verify that the internal height of 1.1 mm is sufficient for the conductor thickness. Consider Material 43 properties for frequencies above 25 MHz where this part demonstrates significant impedance.

Part Context

This part belongs to Fair-Rite's 26 series of flat cable cores. It serves as a passive filter element for signal integrity management. Unlike circular cores, it is specifically engineered to fit the geometry of ribbon cables. It complements other ferrite solutions by addressing noise on multi-line parallel interfaces.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative Fair-Rite flat cores based on matching internal dimensions and impedance curves if substitution is required.
