2631250202

Overview

Fair-Rite 2631250202 is a round cable ferrite core designed for EMI suppression. It utilizes Material 31, providing an impedance of 98 ohms at 25 MHz and 182 ohms at 100 MHz. The component features a single aperture with an inner diameter of 6.35 mm (0.25 inches). External dimensions are 2.95 mm in width/height and 25.4 mm in length. It operates within a frequency range of 25 MHz to 300 MHz.

Feature Summary

• Solid round construction for free-hanging installation on cables
• Material 31 composition optimized for high-frequency noise attenuation
• Single-aperture design facilitates easy sliding onto existing wiring

Applications

• Electromagnetic interference suppression components
• Common mode noise reduction in signal lines
• EMI filtering for electronic equipment cabling

Procurement Notes

Verify the specific impedance requirements against the Material 31 datasheet before ordering. Confirm that the cable diameter fits within the 6.35 mm inner diameter tolerance. Check RoHS compliance status if required by your manufacturing standards. Ensure the operating frequency aligns with the 25 MHz to 300 MHz effective range for optimal performance.

Selection Notes

Select this part when a solid round core is preferred over split types for permanent installations. Material 31 is suitable for frequencies above 10 MHz where higher permeability is needed compared to Material 43. Consider the physical length of 25.4 mm for available space constraints on the cable assembly.

Part Context

This component belongs to Fair-Rite's 26 series of round cable cores. It is distinct from multi-hole or toroidal designs, offering a simple cylindrical geometry. The 2631250202 designation specifically identifies the Material 31 formulation with the 0.25-inch bore size within the manufacturer's catalog.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific combination of Material 31 and 6.35 mm bore.
