2643166651

Overview

Fair-Rite 2643166651 is a split flat cable ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing an impedance of 290 Ohms at 100 MHz. The component features a clip-together design with internal dimensions of 34.42 mm width by 0.84 mm height. External dimensions measure approximately 38.35 mm in length and 28.6 mm in width. The unit operates within a temperature range of -55°C to +125°C.

Feature Summary

• Split construction allows installation on existing flat ribbon cables without disconnecting conductors
• Material 43 composition provides high impedance characteristics for broadband noise attenuation
• Clip-together assembly ensures secure retention around the cable bundle

Applications

• Suppression of common-mode noise on multi-conductor flat ribbon cables
• EMI mitigation in information technology equipment interconnects
• Noise filtering for data transmission lines in electronic assemblies

Procurement Notes

Verify that the specific order quantity matches the manufacturer's standard packaging configuration. Confirm compliance requirements such as RoHS status against current regulatory standards. Ensure the selected material grade aligns with the intended frequency spectrum for effective noise suppression.

Selection Notes

Select this component when flat cable geometry requires non-invasive noise reduction. Material 43 is suitable for frequencies typically encountered in digital signal integrity issues. Verify that the internal width accommodates the target flat cable thickness without excessive clearance.

Part Context

This part belongs to the Fair-Rite 26 series of flat cable cores. These components are engineered specifically for suppressing electromagnetic interference on parallel conductor ribbons. The split design distinguishes them from solid toroidal or bead cores used on round wires.
