2643801202

Overview

The Fair-Rite 2643801202 is a solid round cable ferrite core designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 92 ohms at 100 MHz. The component features an inner diameter of 19.00 mm (0.748 inches), an outer diameter of 29.01 mm (1.142 inches), and a length of 13.84 mm (0.545 inches). This free-hanging design supports cables within the specified bore size.

Feature Summary

• Solid construction with free-hanging installation capability
• Material 43 composition for effective high-frequency noise attenuation
• Round geometry optimized for cylindrical cable applications

Applications

• Electromagnetic interference suppression on power and signal cables
• High-frequency noise filtering in electronic assemblies
• Cable management and shielding in industrial equipment

Procurement Notes

Verify the specific impedance value and physical dimensions against the official Fair-Rite datasheet to ensure compatibility with target cable diameters. Confirm that Material 43 characteristics align with the required frequency range for the intended application. Check RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this part when a large bore size is required for thick cables or bundles. Material 43 is suitable for frequencies above 25 MHz. Ensure the cable diameter fits within the 19.00 mm inner diameter limit. Consider the solid form factor for permanent installations rather than split-core alternatives.

Part Context

This component belongs to the Fair-Rite 26 series of round cable cores. These cores are engineered for EMI suppression using nickel-zinc ferrite materials. The 26 series offers various sizes and material options to address different cable diameters and frequency requirements across diverse electronic systems.
