2643170251

Overview

The Fair-Rite 2643170251 is a split flat cable ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing an impedance of 70 Ohms at 100MHz. The component features a free-hanging installation type with specific dimensional constraints: an inner diameter of 12.70mm (0.500 inches), an outer width of 22.75mm (0.895 inches), an outer height of 3.30mm (0.125 inches), and a length of 12.70mm (0.500 inches).

Feature Summary

• Split design allows installation on existing cables without disconnection.
• Material 43 composition provides high impedance for EMI suppression.
• Flat geometry accommodates ribbon or flat cables.

Applications

• Electromagnetic interference suppression on flat cables.
• Filtering in inductive circuits.
• Enabling side-by-side cable routing with noise reduction.

Procurement Notes

Verify the exact part number against official Fair-Rite documentation to ensure material compatibility and impedance specifications match the target application requirements. Confirm RoHS compliance status if environmental regulations apply to the end product assembly process.

Selection Notes

Select this component when flat cable geometry is required for EMI mitigation. Ensure the cable thickness fits within the 3.30mm height constraint and the inner diameter accommodates the cable bundle. Material 43 is suitable for frequencies around 100MHz where 70 Ohm impedance is necessary.

Part Context

This part belongs to the Fair-Rite Snap-It series of flat cable cores. These components are engineered specifically for ribbon cables and flat wire assemblies. The split construction facilitates retrofitting onto harnesses during manufacturing or maintenance phases without requiring cable termination changes.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Verify cross-compatibility based on impedance curves and physical dimensions before substituting.
