2643180651

Overview

Fair-Rite part number 2643180651 is a solid free-hanging ferrite cable core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, which provides effective noise attenuation in the high-frequency range. The component exhibits an impedance of 33 Ohms at 100 MHz. Physical dimensions include an internal diameter of 11.99 mm (0.472 inches). The product is classified as a solid core type, distinct from split-core variants, and is packaged in bulk quantities.

Feature Summary

• Solid construction suitable for permanent installation on cables
• Material 43 composition optimized for high-frequency noise suppression
• Controlled impedance characteristics for predictable EMI performance

Applications

• Electromagnetic interference suppression on signal cables
• Power line noise filtering
• Data transmission cable protection

Procurement Notes

Verify the specific impedance value and material grade against official Fair-Rite datasheets prior to procurement. Confirm that the solid core design aligns with assembly requirements, as it cannot be opened after placement. Ensure compatibility with the target cable diameter relative to the specified internal dimension.

Selection Notes

Select this component when a fixed, non-removable ferrite solution is required for EMI mitigation. Material 43 is appropriate for frequencies above 10 MHz. Compare physical constraints against available space, noting the internal diameter limits the maximum cable thickness. Consider split-core alternatives if field installation on existing cabling is necessary.

Part Context

This component belongs to the Fair-Rite ferrite cable core family, specifically engineered for suppressing common-mode noise. It differs from multi-aperture or toroidal rings by its single-cable passage design. The 26 series designation typically indicates specific dimensional standards within the manufacturer's catalog for flat or round cable applications.

Replacement Considerations

Direct substitutes must match the 33 Ohm @ 100 MHz impedance and Material 43 specification. Verify internal diameter compatibility with existing cable assemblies. Alternative Fair-Rite part numbers may offer different impedance profiles or physical sizes but require re-validation of EMI performance.
