2631302502

Overview

Fair-Rite 2631302502 is a solid round ferrite cable core designed for EMI suppression. It utilizes Material 31, providing an impedance of 183 Ohms at 100 MHz across a frequency range of 1 MHz to 250 MHz. The component features a 4.29 mm inner diameter, 9.00 mm outer diameter, and a length of 19.05 mm. Packaged in bulk, it serves as a free-hanging shield bead for cable noise reduction.

Feature Summary

• Solid round construction for secure cable fitting
• Material 31 composition for high-frequency attenuation
• Free-hanging design for easy installation

Applications

• EMI suppression on signal cables
• Noise filtering on power lines
• Data bus cable protection

Procurement Notes

Verify the specific impedance tolerance and material batch consistency with Fair-Rite directly, as distributor data may vary slightly. Confirm RoHS compliance status for your region. Ensure the inner diameter matches the target cable bundle size before ordering. Check for any updated datasheet revisions that might affect mechanical dimensions or electrical performance specifications.

Selection Notes

Select this part when high impedance is required above 100 MHz. Material 31 offers superior performance compared to standard mixtures in the VHF/UHF range. Ensure the cable diameter fits within the 4.29 mm bore. Consider the physical length for available space constraints on the harness.

Part Context

This component belongs to the Fair-Rite 2631 series of round cable cores. It is distinct from split cores or snap-on types due to its solid construction. The 2631302502 designation specifically identifies the Material 31 variant with the stated impedance and dimensional profile.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific combination of Material 31, 183 Ohm impedance, and exact dimensions.
