2631625002

Overview

Fair-Rite 2631625002 is a solid round ferrite cable core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 31, providing an impedance of 130 Ohms at 100 MHz. The component features a central bore diameter of 7.9 mm (0.312 inches) and an outer diameter of 15.88 mm (0.625 inches). Its physical length measures 14.28 mm (0.562 inches). This free-hanging design allows for direct installation onto cables without additional mounting hardware.

Feature Summary

• Solid construction with no split design for continuous magnetic path integrity
• Utilizes Material 31 optimized for high-frequency noise absorption
• Free-hanging configuration enables direct sliding onto existing cable assemblies

Applications

• Electromagnetic interference suppression on signal and power cables
• Common mode choke implementation for data lines
• High-frequency noise filtering in electronic equipment cabling

Procurement Notes

Verify the specific impedance requirement matches the application frequency spectrum, as Material 31 performance varies across bands. Confirm that the 7.9 mm inner diameter accommodates the target cable bundle diameter with appropriate clearance. Ensure the operating temperature range of -55°C to 90°C aligns with the environmental conditions of the deployment site. Cross-reference the Mouser part number 623-2631625002 or DigiKey 1934-2631625002-ND for accurate sourcing.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable installations. Material 31 is suitable for applications requiring effective attenuation in the higher frequency range compared to lower permeability materials. The compact dimensions make it ideal for space-constrained wiring harnesses where larger cores cannot fit. Consider split-core alternatives if frequent cable reconfiguration is necessary.

Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. It shares the same Material 31 composition as other parts in the series but differs in physical dimensions and resulting impedance characteristics. The 26 series provides various sizes to accommodate different cable diameters while maintaining consistent material properties for predictable EMI suppression performance across the product line.

Replacement Considerations

Direct substitutes include Fair-Rite 2631625001 or 2631625003 if dimensional variations are acceptable. For identical specifications from other manufacturers, verify equivalent Material 31 formulations and impedance curves at 100 MHz.
