2643022401

Overview

The Fair-Rite Products Corp. 2643022401 is a solid ferrite EMI suppression bead constructed from Material 43. It features a cylindrical design with an inner diameter of 7.11 mm, an outer diameter of 14.28 mm, and a length of 15.24 mm. The component provides a guaranteed minimum impedance of 118 ohms at a test frequency of 100 MHz. Designed for free-hanging installation, it serves as a passive filter to attenuate high-frequency noise on cables.

Feature Summary

• Solid cylindrical construction utilizing Material 43 ferrite composition
• Guaranteed minimum impedance specification for reliable EMI suppression
• Free-hanging installation design suitable for cable wrapping

Applications

• Electromagnetic interference suppression on electronic cables
• High-frequency noise attenuation in signal lines
• Cable filtering in general electronic assemblies

Procurement Notes

Verify the specific impedance tolerance and material grade against the official Fair-Rite datasheet before integration. Confirm that the physical dimensions align with the available cable bundle size. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the part number with current manufacturer documentation to confirm active status.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. Material 43 offers effective performance in the VHF/UHF range. The 7.11 mm inner diameter accommodates cables up to that thickness. Consider the 118-ohm impedance target for the specific noise frequencies present in the application circuit.

Part Context

This component belongs to the Fair-Rite Shield Bead series, which are solid ferrite cores designed for electromagnetic interference suppression. The '26' prefix typically denotes a round cable core product class within the Fair-Rite catalog structure. These beads are distinct from split-core types, offering a more robust mechanical structure for fixed applications.

Replacement Considerations

Consult the Fair-Rite catalog for direct substitutes with identical dimensions or compatible inner diameters. Verify that any replacement maintains the Material 43 composition to ensure similar impedance characteristics at 100 MHz. Check for equivalent impedance values if the original specification is critical.
