2631023002

Overview

Fair-Rite 2631023002 is a solid round ferrite cable core designed for EMI suppression. It utilizes Material 31, providing an impedance of 160 ohms at 100 MHz across a frequency range of 1 to 300 MHz. The component features an inner diameter of 4.9 mm (0.193 inches), an outer diameter of 9.5 mm (0.375 inches), and an external length of 19.05 mm (0.75 inches). Packaged in bulk, it serves as a shield bead for cable noise reduction.

Feature Summary

• Solid round construction for secure cable retention
• Material 31 composition optimized for high-frequency noise attenuation
• Guaranteed minimum impedance specification for reliable EMI suppression

Applications

• Suppression of electromagnetic interference on data cables
• Noise filtering on power supply lines
• EMI mitigation on communication interface cables

Procurement Notes

Verify the specific Material 31 designation and impedance tolerance against the official Fair-Rite datasheet prior to procurement. Confirm that the bulk packaging format aligns with assembly requirements. Ensure the physical dimensions match the cable bundle constraints for proper installation.

Selection Notes

Select this part when high-frequency noise suppression between 1 MHz and 300 MHz is required. Material 31 offers superior performance in the VHF/UHF range compared to lower-frequency materials. Ensure the cable diameter fits within the 4.9 mm inner diameter limit for effective magnetic coupling.

Part Context

This component belongs to the Fair-Rite 26 series of round cable cores. It is distinct from split-core designs, offering a solid toroidal geometry that requires threading the cable through the center aperture. It complements other ferrite solutions by providing targeted attenuation for specific frequency bands using specialized material formulations.

Replacement Considerations

Direct substitutes include Fair-Rite 2631006302, which shares identical physical dimensions but may differ in specific impedance characteristics due to material variations. Verify compatibility with existing cable bundles before substitution.
