2643706001

Overview

Fair-Rite 2643706001 is a solid, free-hanging ferrite cable core designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 45 ohms at 100 MHz. The component features a circular design with an inner diameter of 0.80 mm (0.031 inches), an outer diameter of 3.50 mm (0.138 inches), and a length of 2.70 mm (0.106 inches).

Feature Summary

• Solid construction for secure cable retention without splitting.
• Material 43 composition optimized for high-frequency noise attenuation.

Applications

• Electromagnetic interference suppression on small-diameter cables.
• High-frequency signal line filtering in compact electronic assemblies.

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Fair-Rite datasheet to ensure compatibility with target cable diameters. Confirm Material 43 specifications match the required frequency response characteristics for the intended application environment.

Selection Notes

Select this component when a non-split, solid ferrite bead is required for cables with an inner diameter near 0.80 mm. Material 43 is suitable for applications requiring effective noise suppression in the higher frequency range, typically above 25 MHz.

Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. These components are engineered as solid beads, distinguishing them from split-core alternatives that allow installation after cable termination. The 26 series generally covers various sizes within the Material 43 family.

FAQ

Is the 2643706001 a split-core or solid core?

It is a solid core ferrite bead, meaning the cable must be threaded through before installation.

What is the operating frequency range for Material 43 used in this part?

Material 43 is typically effective for frequencies ranging from 25 MHz to 300 MHz.
