2643178751

Overview

Fair-Rite 2643178751 is a solid flat ribbon cable ferrite core from the 26 series, utilizing Material 43. It provides an impedance of 71 Ohms at 100 MHz. The component features an internal length of 26.5 mm and an external length of 31.5 mm. Designed for electromagnetic interference suppression, it operates within a frequency range of 20 MHz to 300 MHz. The core is supplied in bulk packaging.

Feature Summary

• Solid construction designed specifically for full flat ribbon cables
• Material 43 composition optimized for high-frequency noise suppression
• Controlled impedance characteristics for consistent EMI performance

Applications

• Electromagnetic interference suppression on flat ribbon cables
• High-frequency signal integrity enhancement
• Noise filtering in data transmission lines

Procurement Notes

Verify the specific impedance value against your design requirements, as datasheets may list minimums or ranges rather than a single fixed point. Confirm that the physical dimensions match the target cable width and thickness. Ensure the Material 43 specification aligns with the intended operating frequency band for effective attenuation.

Selection Notes

Select this part when a solid, non-split core is required for permanent installation on flat ribbon cables. Material 43 offers a balanced permeability suitable for general-purpose noise suppression in the VHF/UHF spectrum. Compare internal dimensions against the cable bundle size to ensure proper fit without mechanical stress.

Part Context

This component belongs to Fair-Rite's 26 series of flat cable cores. It shares the Material 43 formulation with other parts in the lineup but differs in physical geometry and impedance rating. It serves as a dedicated solution for flat cable applications where split cores are unsuitable due to space or retention constraints.

Replacement Considerations

Direct substitutes include other Fair-Rite 26 series cores with similar Material 43 properties, such as 2643167851, provided the impedance and dimensional tolerances meet the application needs. Cross-brand replacements require careful verification of material composition and impedance curves.
