2643803802

Overview

The Fair-Rite 2643803802 is a solid round ferrite cable core designed for electromagnetic interference suppression. It utilizes Material 31, providing an impedance of 108 Ohms at 100 MHz. The component features an inner diameter of 35.56 mm and an outer diameter of 60.96 mm, with a length of 12.70 mm. It operates effectively within the frequency range of 1 MHz to 300 MHz.

Feature Summary

• Solid cylindrical construction for secure mounting on cables
• Material 31 composition optimized for high-frequency noise attenuation
• Guaranteed minimum impedance specification for consistent performance

Applications

• Electromagnetic interference suppression on power cables
• Noise reduction in communication signal lines
• Common mode choke applications for broadband frequencies

Procurement Notes

Verify the specific impedance tolerance and material grade against the manufacturer's current datasheet before integration. Confirm that the physical dimensions match the cable assembly requirements. Ensure compliance with relevant environmental regulations such as RoHS if applicable to the final product deployment.

Selection Notes

Select this component when a large aperture is required for thick cables or bundles. Material 31 is suitable for applications requiring effective suppression across a broad frequency spectrum from 1 MHz to 300 MHz. Compare the 108 Ohm impedance rating against the target noise frequencies to ensure adequate attenuation levels are achieved.

Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. These components are engineered specifically for EMI suppression tasks where standard snap-on cores may not fit larger conductors. The solid design distinguishes it from split-core alternatives, offering a permanent installation solution for fixed cabling systems.

Replacement Considerations

Direct substitutes include other Fair-Rite parts with similar Material 31 properties and comparable inner diameters. Verify impedance values at 100 MHz to ensure equivalent noise suppression capabilities. Cross-reference physical dimensions to confirm compatibility with existing cable assemblies.
