2643180451

Overview

Fair-Rite 2643180451 is a solid ferrite cable core designed for flat ribbon cables. It utilizes Material 44, providing an impedance of 45 ohms at 100 MHz. The component features a split design with internal dimensions of 5.99 mm and external dimensions of 31 mm x 27 mm x 6 mm. It accommodates flat cables ranging from 12.7 mm to 77 mm in width. The unit operates within a temperature range of -55°C to 125°C and complies with RoHS standards.

Feature Summary

• Split construction allows installation on existing multi-conductor flat cables without disconnection
• Material 44 composition provides specific high-frequency impedance characteristics for EMI suppression
• Solid free-hanging design suitable for bulk handling and integration into cable assemblies

Applications

• Electromagnetic interference suppression on flat ribbon cables
• Signal integrity enhancement in information products
• Cable assembly manufacturing for data transmission lines

Procurement Notes

Verify the exact material grade and impedance value against the manufacturer's current datasheet, as distributor listings may contain conflicting specifications. Confirm that the split core geometry matches the target flat cable width requirements. Ensure compliance with relevant environmental regulations such as RoHS if required by the end application.

Selection Notes

Select this part when suppressing noise on flat cables rather than round wires. Material 44 is chosen for its specific permeability and loss characteristics at higher frequencies compared to other materials like 43. Ensure the cable width falls within the 12.7 mm to 77 mm range for proper fit and effective suppression performance.

Part Context

This component belongs to Fair-Rite's line of ferrite cable cores specifically engineered for flat ribbon applications. It serves as a passive filter element to attenuate common-mode noise. The product is distinct from snap-on ring cores due to its rectangular cross-section and split housing, which facilitates retrofitting onto wide bus structures.
