2631181381

Overview

Fair-Rite 2631181381 is a split-core ferrite cable snap-it utilizing Material 31. It provides an impedance of 490 Ohms at 1 MHz to 300 MHz, with a test frequency of 100 MHz. The component features a round shape and measures 37.21 mm in length. Designed for solid round cables, it offers a convenient snap-fit assembly without requiring cable disconnection.

Feature Summary

• Snap-fit design allows for easy installation over existing cables
• Utilizes Material 31 for effective high-frequency noise suppression
• Round core geometry accommodates standard cylindrical cabling

Applications

• EMI suppression on round data or power cables
• Common mode noise reduction in electronic assemblies
• Retroactive filtering of cable runs in equipment racks

Procurement Notes

Verify the specific Material 31 designation and impedance tolerance against the manufacturer's current datasheet before integration. Confirm that the internal diameter of the snap-it is sufficient for the target cable outer diameter to ensure a secure mechanical fit. Check RoHS compliance status as required by project specifications.

Selection Notes

Select this component when retrofitting EMI suppression onto pre-existing round cables is required. The Material 31 composition is suitable for applications operating within the 1 MHz to 300 MHz range. Ensure the cable diameter falls within the core's inner bore limits to maintain magnetic coupling effectiveness.

Part Context

This part belongs to Fair-Rite's 26 series of ferrite cable cores. It represents a split-core variant designed for convenience, contrasting with solid cores that require cable termination during installation. The 2631181381 model specifically targets higher impedance requirements compared to lower-impedance variants in the same family.
