2643167551

Overview

Fair-Rite 2643167551 is a free-hanging ferrite cable core designed for flat ribbon cable EMI suppression. It utilizes Material 43, providing an impedance of 480 Ohms at 100 MHz. The component features an internal diameter of 33.20 mm and external dimensions of 52.90 mm width by 12.50 mm height. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Accommodates multi-conductor flat cables with widths ranging from 12.7 mm to 77 mm
• Provides electromagnetic interference suppression through high impedance characteristics
• Constructed from Material 43 for effective noise reduction in specified frequency ranges

Applications

• Suppression of electromagnetic interference on multi-conductor flat cables
• Noise filtering for wide ribbon cable assemblies
• EMI mitigation in electronic equipment utilizing flat cabling

Procurement Notes

Verify the specific impedance value and material composition against the manufacturer's official datasheet before procurement. Confirm that the internal diameter accommodates the target flat cable width. Ensure compliance with RoHS standards if required by the application environment. Cross-reference the part number with authorized distributors to ensure authenticity.

Selection Notes

Select this component when suppressing noise on wide flat cables requiring high impedance at 100 MHz. The Material 43 composition is suitable for general-purpose EMI suppression. Ensure the physical dimensions fit the available space and the cable width falls within the 12.7 mm to 77 mm operational range. Consider thermal limits up to +125°C during selection.

Part Context

This part belongs to Fair-Rite's series of flat cable ferrite cores. These components are specifically engineered to slide over or enclose flat ribbon cables to attenuate common-mode noise. They are distinct from circular cable cores and toroidal rings, offering a form factor optimized for flat conductor geometries.
