2631801202

Overview

Fair-Rite 2631801202 is a solid round ferrite cable core utilizing Material 31 for EMI suppression. It features an inner diameter of 19.00 mm (0.748 inches), an outer diameter of 29.01 mm (1.142 inches), and an external length of 13.84 mm (0.545 inches). The component provides a minimum impedance of 88 Ohms at a test frequency of 100 MHz, operating within the 1 MHz to 300 MHz range.

Feature Summary

• Solid round construction designed for free-hanging installation on cables
• Material 31 composition optimized for high-frequency noise attenuation
• Guaranteed minimum impedance specifications for reliable EMI control

Applications

• Suppression of electromagnetic interference on power and signal cables
• Common mode noise reduction in electronic assemblies
• EMI mitigation in amateur radio equipment

Procurement Notes

Verify availability directly with Fair-Rite or authorized distributors as lead times may vary. Confirm that the specific lot meets Material 31 specifications. Ensure the cable diameter fits within the 19.00 mm inner diameter tolerance before ordering.

Selection Notes

Select this part when a large aperture is required for thick cables. Material 31 is suitable for frequencies above 10 MHz. Compare impedance requirements against other 26-series cores if lower attenuation is acceptable.

Part Context

This component belongs to the Fair-Rite 26 series of EMI suppression cores. It is distinct from split cores due to its solid design, requiring cable ends to be accessible during installation. It serves as a passive filter element in high-noise environments.
