2643023201

Overview

Fair-Rite Products Corp. part number 2643023201 is a solid free-hanging ferrite core designed for electromagnetic interference suppression. Constructed from Fair-Rite Material 43, this component provides an impedance of 30 ohms at a test frequency of 100 MHz. The physical dimensions include an internal diameter of 1.73 mm (0.068 inches), an external diameter of 2.85 mm (0.112 inches), and a length of 3.73 mm (0.147 inches). It is classified as a cable ferrite suitable for round wire applications.

Feature Summary

• Solid construction with a free-hanging design for easy installation on cables
• Utilizes Material 43 composition for effective high-frequency noise attenuation
• Round cylindrical geometry optimized for single-conductor wire wrapping

Applications

• Electromagnetic interference suppression on signal and power cables
• Common mode noise reduction in electronic assemblies
• Cable filtering for compliance with emission standards

Procurement Notes

Verify the specific Material 43 composition and impedance characteristics against current Fair-Rite datasheets prior to integration. Confirm that the internal diameter accommodates the target cable gauge without excessive friction or clearance issues. Ensure the solid bead format aligns with the mechanical constraints of the assembly environment.

Selection Notes

Select this component when low impedance values are required for broadband noise suppression. The Material 43 formulation offers a balanced permeability profile suitable for frequencies ranging from tens to hundreds of megahertz. Consider the small physical footprint for space-constrained designs requiring minimal addition to cable bulk.

Part Context

This part belongs to the Fair-Rite 26 series of solid ferrite cores. These components are distinct from split beads or toroidal rings, offering a permanent magnetic path around a single conductor. The 26 series is widely used in general-purpose EMI mitigation where fixed impedance characteristics are preferred over adjustable solutions.

Replacement Considerations

Direct substitutes must match the 30-ohm impedance at 100 MHz and Material 43 composition. Verify dimensional compatibility, specifically the 1.73 mm inner diameter, to ensure fitment on existing cable assemblies without redesigning connector interfaces.
