2643626502

Overview

Fair-Rite part number 2643626502 is a solid round cable ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing effective broadband performance across frequencies from 25 MHz to 300 MHz. The component features an inner diameter of 10.15 mm and an outer diameter of 18.7 mm, with a total height of 50.8 mm. This geometry accommodates cables up to the specified inner diameter limit while maintaining structural integrity for free-hanging installation.

Feature Summary

• Solid construction provides mechanical stability for direct cable mounting without split halves
• Material 43 composition ensures high impedance characteristics in the 25 MHz to 300 MHz range
• Round profile allows uniform magnetic flux distribution around the enclosed conductor

Applications

• Electromagnetic interference suppression on power and signal cables
• Broadband noise filtering in electronic assemblies
• Cable management and EMI control in industrial equipment

Procurement Notes

Verify the specific material grade matches the required frequency response, as Material 43 is optimized for the 25-300 MHz range. Confirm physical dimensions align with available cable diameters, specifically ensuring the cable fits within the 10.15 mm inner diameter. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the solid design suits the installation environment compared to split-core alternatives.

Selection Notes

Select this component when broadband attenuation between 25 MHz and 300 MHz is required. Material 43 offers a balanced permeability suitable for general-purpose EMI suppression. The solid design is preferred over split cores for permanent installations where disassembly is not needed. Verify that the 50.8 mm length provides sufficient impedance for the specific noise spectrum present in the application.

Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. These components are widely used in electronics manufacturing for cable harnessing. The 2643626502 designation specifically identifies the CS19/10/51-43 configuration, distinguishing it by its unique dimensional ratios and material selection within the broader ferrite core catalog.
