2643178551

Overview

Fair-Rite 2643178551 is a solid, free-hanging ferrite cable core designed for EMI suppression on flat ribbon cables. It utilizes Fair-Rite Material 43, providing an impedance of 82 Ohms at 100 MHz. The component features a rectangular cross-section with an internal dimension of 21.49 mm width by 1.60 mm height and an external dimension of 26.49 mm width by 26.0 mm height. The total length is 38.85 mm. This part is RoHS compliant and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Solid construction provides stable mechanical support for flat ribbon cables without splitting.
• Material 43 composition offers effective high-frequency noise attenuation characteristics.
• Free-hanging design allows for easy installation onto existing cable assemblies.

Applications

• Suppression of electromagnetic interference on flat ribbon data cables
• Noise filtering in high-speed digital signal transmission lines
• EMI control in computer peripheral interconnects

Procurement Notes

Verify the specific impedance tolerance requirements against the manufacturer's datasheet, as minimum impedance values are specified for marked frequencies. Confirm that the internal dimensions match the target flat cable thickness and width to ensure proper fit. Check for RoHS3 compliance status if required by project specifications.

Selection Notes

Select this model when a non-split, solid core is preferred over split cores for permanent installations. Material 43 is suitable for frequencies typically between 10 MHz and several hundred MHz. Ensure the cable fits within the 21.49 mm x 1.60 mm internal aperture. Consider thermal limits if operating near the maximum rated temperature.

Part Context

This component belongs to the Fair-Rite 26 series of ferrite cable cores. It is distinct from split-core variants (such as 2643167851) which allow installation after cable termination. The 2643178551 is manufactured specifically for flat ribbon applications, differing from round cable beads or toroidal rings used for single conductors.

FAQ

Is the 2643178551 a split core?

No, it is a solid core design intended for installation before cable termination or during manufacturing.

What material is used in this core?

It uses Fair-Rite Material 43, which is optimized for high-frequency noise suppression.
