2643004701

Overview

Fair-Rite 2643004701 is a solid free-hanging ferrite cable core from the 26 series, utilizing Material 43. It features an inner diameter of 2.29 mm (0.090 inches), an outer diameter of 4.75 mm, and an external length of 12.7 mm. The component provides an impedance of 26 ohms at a test frequency of 100 MHz. Designed for EMI suppression, it operates effectively within a frequency range of 25 MHz to 300 MHz.

Feature Summary

• Solid construction designed as a free-hanging shield bead for direct cable application
• Material 43 composition optimized for high-frequency noise attenuation in the VHF/UHF spectrum
• Round cross-section geometry facilitates easy installation over existing wire harnesses

Applications

• EMI suppression on data cables operating in the 25-300 MHz range
• Noise filtering for USB, HDMI, or similar signal lines
• Common mode choke applications for high-speed digital interfaces

Procurement Notes

Verify the specific impedance value and material grade against the manufacturer's current datasheet before integration. Confirm that the inner diameter accommodates the target cable bundle without excessive friction or deformation. Ensure the selected packaging quantity aligns with production volume requirements, as bulk packaging may require separate handling procedures.

Selection Notes

Select this component when a solid, non-split ferrite bead is required for permanent installation on cables. Material 43 is suitable for frequencies above 25 MHz, making it distinct from lower-frequency materials. Compare the 26 mm OD family dimensions against available space constraints to ensure mechanical fit within the assembly enclosure.

Part Context

The 2643004701 belongs to Fair-Rite's 26 series of round cable cores. This series typically includes various inner diameters and lengths to suit different cable sizes while maintaining consistent outer dimensions for standardized mounting solutions. The part utilizes the proprietary Material 43 formulation known for its resistive characteristics in the VHF band.

Replacement Considerations

Direct substitutes include other Fair-Rite 26 series parts with identical 4.75 mm OD and 12.7 mm length but different inner diameters if cable size varies. Cross-manufacturer equivalents must match the 26 Ohm @ 100 MHz impedance profile and Material 43 permeability characteristics to maintain circuit performance.
