2643180751

Overview

The Fair-Rite 2643180751 is a solid, free-hanging ferrite core designed for flat cable applications. It utilizes Material 43 to provide electromagnetic interference suppression. The component features an internal diameter of 2.268 inches (57.60 mm) and an external width of 0.264 inches (6.70 mm). The length measures 0.472 inches (11.99 mm). It exhibits an impedance of 76 Ohms at 100 MHz, with effective frequency operation ranging from 25 MHz to 300 MHz.

Feature Summary

• Constructed from Material 43 ferrite for high-frequency common-mode choke performance
• Solid design suitable for flat ribbon cables
• Free-hanging installation type for flexible integration

Applications

• EMI suppression on flat data cables
• High-frequency common-mode chokes
• Information technology equipment signal integrity

Procurement Notes

Verify the specific Material 43 composition and impedance characteristics against your schematic requirements. Confirm that the physical dimensions accommodate the target flat cable thickness. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the part number with official Fair-Rite documentation to confirm current production status.

Selection Notes

Select this component when managing EMI on wide flat cables requiring substantial aperture size. Material 43 offers optimal permeability for the specified frequency range. Compare the 76 Ohm impedance profile against other materials if lower or higher attenuation is needed. Ensure the solid core geometry fits within the available spatial constraints of the assembly.

Part Context

This component belongs to the Fair-Rite 26 series of cable ferrites. It is distinct from split cores or toroidal rings due to its solid, one-piece construction. The 2643180751 is specifically engineered for flat cabling rather than round wires. It serves as a passive filter element in digital and analog signal lines.

Replacement Considerations

No public confirmed substitute part numbers are available.
