2643171051

Overview

Fair-Rite Products Corp. part number 2643171051 is a split flat ribbon cable ferrite core designed for EMI suppression. It utilizes Material 43, providing an impedance of 112 ohms at 100 MHz. The component features a clip-style design with external dimensions of 26.67 mm in length and 8.4 mm in width. Internal dimensions include a height of approximately 0.84 mm to accommodate flat cables. The unit is supplied in bulk packaging and complies with RoHS3 standards.

Feature Summary

• Split construction allows installation onto existing flat ribbon cables without disconnecting the circuit.
• Material 43 composition provides high magnetic permeability for effective noise attenuation in the frequency range above 10 MHz.
• Clip-style geometry ensures secure retention on flat conductors while maintaining controlled impedance characteristics.

Applications

• Suppression of electromagnetic interference on parallel flat ribbon cables in digital data buses.
• Noise reduction on internal computer bus connections such as IDE or SATA interfaces.
• EMI mitigation on peripheral device cabling within electronic assemblies.

Procurement Notes

Verify that the specific order references Fair-Rite manufacturer part number 2643171051 to ensure correct Material 43 composition and 112-ohm impedance profile. Confirm physical compatibility with the target flat cable thickness prior to procurement, as the internal height is limited. Check for RoHS3 compliance requirements if applicable to the final assembly regulations.

Selection Notes

Select this component when dealing with flat ribbon cables requiring moderate noise suppression in the VHF range. Material 43 is suitable for frequencies typically between 10 MHz and several hundred MHz. Ensure the flat cable fits within the internal height constraints of the split core. Consider alternative materials if operation extends significantly beyond standard digital switching frequencies.

Part Context

This component belongs to the Fair-Rite 26 series of ferrite cable cores. The 26 series encompasses various shapes including round beads, split rings, and flat ribbon clips. Part number 2643171051 specifically denotes a split flat core using Material 43. This series is widely used for passive EMI filtering in consumer electronics and industrial equipment.

Replacement Considerations

Direct substitutes must match the 112-ohm impedance at 100 MHz and Material 43 formulation. Verify that any replacement split flat core accommodates the same cable width and thickness. Generic ferrite clips may not provide the precise impedance control specified by Fair-Rite for this application.
