2643802702

Overview

The Fair-Rite 2643802702 is a solid, free-hanging round ferrite core designed for EMI suppression on cables. It utilizes Material 43, providing an impedance of 80 ohms at 100 MHz. The component features a cylindrical geometry with an inner diameter of 0.900 inches (22.86 mm), an outer diameter of 1.400 inches (35.56 mm), and a length of 0.500 inches (12.70 mm). This configuration allows it to be slipped onto wires without permanent mounting hardware.

Feature Summary

• Constructed from Material 43 ferrite composition for high-frequency noise attenuation
• Solid cylindrical design suitable for free-hanging installation on cables
• Provides inductive common-mode choke functionality for EMI suppression

Applications

• High frequency common-mode chokes
• Cable EMI suppression components
• Inductive applications requiring ferrite cores

Procurement Notes

Verify the specific Material 43 designation and impedance characteristics against current manufacturer datasheets before integration. Confirm that the physical dimensions match the cable bundle requirements. Ensure compliance with relevant environmental regulations such as RoHS if applicable to the final assembly. Cross-reference part numbers with authorized distributors to ensure authenticity.

Selection Notes

Select this component when a solid, non-split ferrite core is required for cables with diameters up to 0.900 inches. Material 43 is appropriate for frequencies typically ranging from 10 MHz to several hundred MHz. Consider the 80-ohm impedance rating at 100 MHz to ensure adequate attenuation 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 mitigating electromagnetic interference on power and signal lines. The 2643802702 specifically represents a larger size variant within the Material 43 product line, offering substantial mass for effective noise absorption on thicker cables.

Replacement Considerations

Direct substitutes must match the 0.900-inch inner diameter and Material 43 composition. Alternative Fair-Rite part numbers with identical dimensions but different materials will alter impedance characteristics. Verify cross-references with other manufacturers only if exact dimensional and material specifications are confirmed.
