2643166851

Overview

The Fair-Rite Products Corp. 2643166851 is a split flat cable ferrite core designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 235 Ohms at 100 MHz across a frequency range of 25 MHz to 300 MHz. The component features a clip-together design where two units form one assembly. Internal dimensions are 26.67 mm width by 0.84 mm height, while external dimensions measure 38.10 mm width by 6.35 mm height and 25.40 mm length.

Feature Summary

• Split flat cable design allowing installation on existing ribbon cables without disconnection
• Material 43 composition optimized for high-frequency noise attenuation in the VHF/UHF spectrum
• Clip-together construction requiring two pieces to secure around the cable

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Noise filtering in computer peripheral connections
• Signal integrity enhancement in high-speed digital data lines

Procurement Notes

Verify the specific Material 43 designation and impedance value of 235 Ohms at 100 MHz against project requirements. Confirm that the clip-together mechanism aligns with the target cable thickness, noting that two units constitute a single functional assembly. Ensure compliance with RoHS3 standards if required by the end-use environment.

Selection Notes

Select this component when dealing with flat ribbon cables rather than round wires, as the internal width accommodates specific cable profiles. The Material 43 selection is appropriate for frequencies above 25 MHz. Consider the physical constraint that two separate cores must be purchased and clipped together to enclose the cable completely.

Part Context

This part belongs to the Fair-Rite 26 series of flat cable cores. These components are distinct from solid or toroidal ferrites due to their split geometry, which facilitates retroactive installation on terminated cables. They are commonly used in consumer electronics and industrial equipment to meet regulatory emissions standards.

Replacement Considerations
