2643250402

Overview

Fair-Rite Products Corp. part number 2643250402 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43 and exhibits an impedance of 102 ohms at 100MHz. The component features a circular geometry with an inner diameter of 0.125 inches (3.18mm), an outer diameter of 0.250 inches (6.35mm), and a length of 0.500 inches (12.70mm). It is currently active in production and complies with RoHS3 standards.

Feature Summary

• Solid construction provides structural integrity for cable clamping without requiring split halves or assembly hardware.
• Material 43 composition offers high magnetic permeability optimized for noise suppression in the 25MHz to 300MHz frequency range.
• Free-hanging design allows for direct installation onto cables without additional mounting brackets or adhesives.

Applications

• Electromagnetic interference suppression on signal and power cables
• Common mode choke implementation for high-frequency noise reduction
• Cable filtering in electronic equipment chassis

Procurement Notes

Verify the specific ordering suffix matches the required impedance and material grade. Confirm physical dimensions align with cable outer diameters before integration. Check current RoHS compliance status against regional regulatory requirements. Ensure storage conditions prevent moisture absorption despite low sensitivity classification.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable attachment. Material 43 is suitable for applications targeting noise frequencies above 25MHz. Ensure the cable diameter fits within the 3.18mm inner diameter constraint. Consider thermal environment limits associated with ferrite materials during operation.

Part Context

This component belongs to the Fair-Rite 2643 series of solid ferrite cores. These parts are distinct from split-core designs as they must be threaded onto cables during manufacturing. The 2643 series generally utilizes Material 43 for broadband noise suppression applications across various industrial and commercial electronics sectors.

Replacement Considerations

No public substitute part numbers are documented for this specific configuration.
