2643168351

Overview

Fair-Rite part number 2643168351 is a split flat cable ferrite core constructed from Material 43. It provides an impedance of 280 Ohms at 100 MHz. The component features an internal diameter of 76.20 mm (3.000 inches) and external dimensions of 88.90 mm width by 6.48 mm height. The length measures 1.125 inches.

Feature Summary

• Split design allows installation around existing cables without disconnection
• Material 43 composition optimized for high-frequency noise suppression
• Controlled impedance characteristics ensure consistent EMI performance

Applications

• Electromagnetic interference suppression on multi-conductor flat ribbon cables
• Noise filtering for wide data buses and parallel interfaces
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Fair-Rite datasheet before procurement. Confirm that the Material 43 specification aligns with the target frequency range requirements. Ensure the split core geometry accommodates the specific flat cable width being treated.

Selection Notes

Select this component when treating wide flat cables requiring significant aperture size. The Material 43 formulation is suitable for frequencies typically above 10 MHz. Compare the 280 Ohm impedance rating against other available values to match the specific noise spectrum profile of the application.

Part Context

This part belongs to the Fair-Rite 26 series of flat cable suppression cores. These components are engineered specifically for accommodating flat ribbon cables with widths ranging from 12.7 mm up to 77 mm. They serve as passive filters to attenuate common-mode noise on parallel data lines.

Replacement Considerations

Check Fair-Rite documentation for alternative impedance values within the same series. Verify compatibility with Material 43 specifications if substituting with similar split cores from other manufacturers.
