2643168251

Overview

Fair-Rite 2643168251 is a split ferrite core designed for flat ribbon cable EMI suppression. It utilizes Material 43, providing an impedance of 125 ohms at 100 MHz and 110 ohms at the same frequency per some sources. The component features a clip-together design with two halves forming one assembly. Dimensions are 52.07 mm in length, 2.050 inches (approx. 52.07 mm) width, and 0.033 inches height. Operating temperature range is -55°C to +125°C.

Feature Summary

• Split clip-together design allows installation on existing cables without disconnection
• Material 43 composition optimized for high permeability in the HF/VHF range
• Specifically engineered for flat ribbon cable geometries

Applications

• EMI suppression on flat ribbon cables
• High-frequency noise reduction in data lines
• Signal integrity enhancement in HF/VHF circuits

Procurement Notes

Verify the specific impedance value required for your application, as sources cite both 125 ohms and 110 ohms at 100 MHz. Confirm that the split design meets mechanical constraints. Ensure Material 43 characteristics align with target frequency interference profiles. Check RoHS compliance status if mandated by project specifications.

Selection Notes

Select this part when dealing with flat ribbon cables requiring non-invasive noise suppression. Material 43 is suitable for frequencies above 1 MHz. The split form factor is critical for retrofits or assemblies where cable removal is impractical. Compare impedance requirements against other materials if lower frequency performance is needed.

Part Context

This component belongs to Fair-Rite's 26 series of EMI suppression cores. The series includes toroidal, round cable, and bead variants. The 26 series is widely used for general-purpose electromagnetic interference mitigation in electronic assemblies.
