2643166551

Overview

Fair-Rite 2643166551 is a solid, free-hanging ferrite core designed for flat ribbon cables. It utilizes Material 43 to provide an impedance of 300 ohms at 100 MHz. The component features internal dimensions of 34.42 mm width by 1.52 mm height and external dimensions of 45.09 mm width by 4.90 mm height. The total length measures 28.58 mm. This split-core design allows for installation over existing cable assemblies without disconnection.

Feature Summary

• Split construction enables installation on terminated cables
• Material 43 composition provides high impedance in the VHF range
• Solid design ensures structural integrity during handling

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Common mode noise reduction in data transmission lines
• Signal integrity enhancement in computer peripheral connections

Procurement Notes

Verify the specific Material 43 designation and impedance rating against your schematic requirements. Confirm that the internal width accommodates the target flat cable thickness. Check RoHS compliance status if required by your manufacturing standards. Ensure the split-core mechanism functions correctly for your assembly process.

Selection Notes

Select this part when high impedance is needed for flat cables in the VHF spectrum. Compare internal dimensions with the cable bundle size to ensure a secure fit. Consider Material 43 characteristics for broadband noise absorption. Evaluate the split design benefits versus solid cores for maintenance accessibility.

Part Context

This component belongs to Fair-Rite's series of split ferrite cores intended for EMI suppression. It complements solid cores by offering retrofit capability. The product line focuses on providing reliable noise filtering solutions for various cable geometries and frequency ranges.

Replacement Considerations

Check Fair-Rite datasheets for other Material 43 split cores with compatible internal widths. Verify impedance curves match your specific frequency noise profile. Ensure physical dimensions allow for similar mounting constraints.
