2643023402

Overview

Fair-Rite Products Corp. part number 2643023402 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. Constructed from Fair-Rite Material 43, this cylindrical component provides an impedance of 120 Ohms at 100 MHz. The physical dimensions include an inner diameter of 4.90 mm (0.193 inches), an outer diameter of 9.53 mm (0.375 inches), and a length of 15.88 mm (0.625 inches). It operates within a temperature range of -55°C to +90°C.

Feature Summary

• Solid construction with a free-hanging design for easy cable installation
• Utilizes Material 43 composition for effective high-frequency noise attenuation
• Cylindrical geometry optimized for slip-on application over conductors

Applications

• Electromagnetic interference suppression on cables
• Common mode choke applications for signal lines
• Noise filtering in electronic assemblies

Procurement Notes

Verify the specific Material 43 composition and impedance characteristics against your frequency requirements. Confirm that the inner diameter accommodates the target cable or wire gauge without excessive force. Ensure the operating temperature range meets the environmental conditions of the intended deployment site.

Selection Notes

Select this component when a solid, non-split ferrite bead is required for permanent installation. Material 43 is suitable for frequencies typically between 10 MHz and several hundred MHz. Compare the 4.90 mm inner diameter against available cable sizes to ensure proper fit and sufficient magnetic coupling for the desired suppression level.

Part Context

This component belongs to the Fair-Rite series of EMI suppression cores. It is distinct from split-core variants, offering a more secure fit on cables during manufacturing. The Material 43 formulation is widely used for general-purpose noise suppression in digital and RF circuits.
