2631102002

Overview

Fair-Rite 2631102002 is a solid round ferrite cable core designed for EMI suppression. It utilizes Material 31, providing an impedance of 260 Ohms at a test frequency of 100 MHz. The component features an inner diameter of 12.83 mm (0.505 inches), an outer diameter of 25.91 mm (1.020 inches), and an external length of 28.58 mm (1.125 inches). It operates effectively within the 1 MHz to 300 MHz frequency range. The unit is supplied in bulk packaging.

Feature Summary

• Solid cylindrical construction for secure cable retention
• Material 31 composition optimized for high-frequency noise attenuation
• Free-hanging installation design compatible with standard cabling

Applications

• Suppression of electromagnetic interference on power cables
• Noise reduction on data transmission lines
• EMI filtering in electronic equipment assemblies

Procurement Notes

Verify material grade and impedance specifications against current Fair-Rite datasheets prior to procurement. Confirm RoHS compliance status and REACH registration details for regulatory adherence. Ensure physical dimensions match the target cable diameter to guarantee proper fit and effective magnetic coupling during installation.

Selection Notes

Select this component when targeting noise frequencies between 1 MHz and 300 MHz. The 12.83 mm inner diameter accommodates cables up to that size. Material 31 is suitable for general-purpose EMI suppression where moderate permeability is required. Verify that the 260 Ohm impedance at 100 MHz meets the specific circuit noise requirements.

Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. The numbering system indicates Product Class 26 and Material Grade 31. These components are widely used in industrial and commercial electronics for common-mode noise suppression without requiring soldering or complex mounting hardware.

Replacement Considerations

Cross-reference with other Material 31 cores from Fair-Rite having similar inner diameters. Verify impedance curves at specific operating frequencies to ensure equivalent performance. Check dimensional tolerances to confirm mechanical compatibility with existing cable assemblies.
