2631625102

Overview

Fair-Rite 2631625102 is a solid round ferrite cable core designed for EMI suppression. It utilizes Material 31, providing an impedance of 260 ohms at 100 MHz. The component features a cylindrical shape with a 7.93 mm inner diameter and a 15.88 mm outer diameter. Its external length measures 28.58 mm. This free-hanging core is intended for clamping over cables to attenuate high-frequency noise.

Feature Summary

• Solid cylindrical construction for secure cable clamping
• Material 31 composition optimized for broadband noise suppression
• Guaranteed minimum impedance specification for consistent performance

Applications

• Cable EMI suppression
• High-frequency noise attenuation
• Signal integrity enhancement

Procurement Notes

Verify the specific Material 31 designation and impedance tolerance against the official Fair-Rite datasheet before integration. Confirm that the 7.93 mm inner diameter accommodates the target cable bundle without excessive force or loose fit. Ensure compliance with RoHS3 standards if required by the end product specifications.

Selection Notes

Select this part when a guaranteed minimum impedance of 260 ohms at 100 MHz is required for noise reduction. The Material 31 formulation is suitable for applications targeting frequencies between 1 MHz and 300 MHz. Ensure the cable diameter fits within the 7.93 mm bore size for effective magnetic coupling.

Part Context

This component belongs to the Fair-Rite 26 series of round cable cores. These cores are widely used in electronic assemblies to mitigate electromagnetic interference on data and power lines. The 2631625102 variant specifically employs Material 31, distinguishing it from other materials like 43 or 61 which offer different permeability characteristics.

Replacement Considerations

Direct substitutes include Fair-Rite 2643625102 (Material 43) or 2661626402 (Material 61), provided the impedance profile matches the design requirements. Verify that alternative materials do not alter the frequency response curve significantly.
