2631101902

Overview

Fair-Rite 2631101902 is a solid round cable ferrite core designed for EMI suppression. It utilizes Material 31, providing a guaranteed minimum impedance of 270 ohms at a test frequency of 100 MHz. The component features an inner diameter of 13.79 mm (0.543 inches), an outer diameter of 28.50 mm (1.122 inches), and an external length of 28.58 mm (1.125 inches). It operates effectively within the 1 MHz to 300 MHz frequency range and is supplied in bulk packaging.

Feature Summary

• Solid cylindrical construction for secure cable retention
• Material 31 composition optimized for high-frequency noise attenuation
• Guaranteed minimum impedance specification for consistent performance

Applications

• Suppression of electromagnetic interference on cables with diameters up to 13.79 mm
• Noise filtering in electronic equipment cabling
• Signal integrity enhancement in high-frequency data transmission lines

Procurement Notes

Verify material composition and impedance specifications against current Fair-Rite datasheets prior to procurement. Confirm physical dimensions match cable requirements. Check RoHS compliance status as manufacturing processes may evolve. Ensure ordering suffixes align with specific packaging or testing requirements defined by the manufacturer.

Selection Notes

Select this component when targeting noise frequencies between 1 MHz and 300 MHz. Ensure the cable diameter fits within the 13.79 mm inner diameter limit. Material 31 is suitable for applications requiring significant impedance at higher frequencies. Compare alternative materials if lower frequency performance or different impedance characteristics are required.

Part Context

This part belongs to the Fair-Rite 2631 series of round cable cores. These components are engineered specifically for EMI suppression rather than inductive energy storage. The series offers various materials and sizes to accommodate different cable diameters and frequency targets, serving as passive filters for conducted emissions.

Replacement Considerations

Substitute parts must match the 13.79 mm inner diameter and provide comparable impedance at 100 MHz. Verify that alternative materials offer similar frequency response characteristics. Physical length and outer diameter constraints should be evaluated for mechanical fit in the assembly.
