2643178351

Overview

Fair-Rite 2643178351 is a solid flat ribbon cable core from the Series 26 line, designed for electromagnetic interference suppression. It utilizes Material 43 to provide an impedance of 82 ohms at 25 MHz and 72 ohms at 100 MHz across a frequency range of 25 MHz to 300 MHz. The component features a full split design with internal dimensions of 13.5 mm in length and 1.35 mm in height, and external dimensions of 13.49 mm by 1.60 mm.

Feature Summary

• Solid construction with a full split design for easy installation on cables
• Material 43 composition optimized for high-frequency noise attenuation
• Compact physical profile suitable for tight spaces in flat ribbon applications

Applications

• Electromagnetic interference suppression on flat ribbon cables
• High-frequency signal integrity management in data transmission lines
• Noise reduction in compact electronic assemblies requiring slim profiles

Procurement Notes

Verify the specific impedance value required for your application, as sources list both 82 ohms at 25 MHz and 72 ohms at 100 MHz. Confirm that the Material 43 specification aligns with your frequency response needs. Ensure the solid split design fits the physical constraints of your cable bundle. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when a low-profile solution for flat ribbon cables is necessary. Material 43 offers effective performance in the 25 MHz to 300 MHz range. The solid split design allows for retrofitting onto existing cables without disconnection. Consider the internal height of 1.35 mm to ensure compatibility with the cable thickness.

Part Context

This part belongs to Fair-Rite's Series 26 flat cable cores, which are engineered specifically for suppressing common-mode noise on flat ribbon cables. These cores are widely used in digital electronics where space is limited and high-frequency interference must be mitigated effectively.
