2631540002

Overview

Fair-Rite 2631540002 is a solid round ferrite cable core designed for EMI suppression. It utilizes Material 31, optimized for lower and broadband frequencies between 1 MHz and 300 MHz. The component provides a guaranteed minimum impedance of 300 ohms at 100 MHz. Physical dimensions include an inner diameter of 6.35 mm (0.250 inches), an outer diameter of 9.65 mm (0.380 inches), and a length of 7.37 mm (0.290 inches).

Feature Summary

• Solid construction with free-hanging installation design.
• Material 31 composition targets lower frequency noise suppression.
• Guaranteed minimum impedance specification for reliable filtering.

Applications

• EMI suppression on cables in the 1 MHz to 300 MHz range.
• Broadband noise reduction applications.
• Lower frequency interference mitigation.

Procurement Notes

Verify current availability directly with Fair-Rite or authorized distributors, as lead times may vary. Confirm RoHS3 compliance status during ordering. Ensure the specified material 31 matches the target frequency requirements for the specific application environment before finalizing procurement.

Selection Notes

Select this part when low-frequency EMI suppression is required within the 1-300 MHz spectrum. The 6.35 mm inner diameter accommodates cables up to that size. Material 31 offers higher permeability suitable for lower frequencies compared to other common ferrite materials.

Part Context

This component belongs to the Fair-Rite Round Cable EMI Suppression Cores category. It is distinct from split cores due to its solid design, requiring cable ends to be threaded through. It serves as a passive filter element integrated directly onto wiring harnesses.

Replacement Considerations

Substitutes must match the 6.35 mm inner diameter and provide comparable impedance at 100 MHz. Verify that alternative materials offer similar performance characteristics for the specific frequency band of interest.
