2643173351

Overview

The Fair-Rite 2643173351 is a solid flat ribbon cable ferrite core designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 88 Ohms at a test frequency of 100 MHz within the 25 MHz to 300 MHz operational range. The component features a free-hanging design with internal dimensions of 19.99 mm width by 0.76 mm height and external dimensions of 24.51 mm width by 5.00 mm height. The total length is 11.99 mm. It operates reliably between -55°C and +125°C and complies with RoHS standards.

Feature Summary

• Solid construction made from Material 43 for effective high-frequency noise attenuation
• Flat geometry specifically engineered for sliding onto ribbon cables
• Free-hanging installation method requiring no additional mounting hardware

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Noise filtering in digital signal transmission lines
• Compliance enhancement for electronic assemblies utilizing flat cabling

Procurement Notes

Verify that the specific order matches the manufacturer part number 2643173351 to ensure correct Material 43 composition and impedance characteristics. Confirm physical compatibility with the target flat cable dimensions prior to procurement. Request official datasheets or compliance certificates directly from authorized distributors to validate RoHS status and material specifications against current regulatory requirements.

Selection Notes

Select this component when flat ribbon cables require passive noise suppression without adding bulk or requiring complex mounting structures. The Material 43 formulation is optimal for broadband interference reduction in the specified frequency range. Ensure the cable thickness fits within the 0.76 mm internal height constraint to allow proper engagement with the core aperture.

Part Context

This component belongs to the Fair-Rite 26 series of cable ferrites, which are dedicated to suppressing common-mode currents on various cable types. The 2643173351 variant specifically addresses flat ribbon applications, distinguishing it from round bead cores or split-core designs used for single conductors. It represents a standard solution for integrating EMI mitigation directly into cable harnesses.
