2643375102

Overview

Fair-Rite Products Corp. part number 2643375102 is a solid, free-hanging ferrite core designed for EMI suppression applications. It utilizes Fair-Rite Material 43, providing an impedance of 50 ohms at 100 MHz. The component features a circular design with an inner diameter of 4.88 mm (0.192 inches), an outer diameter of 7.62 mm (0.300 inches), and a length of 12.70 mm (0.500 inches). It is classified as a cable ferrite suitable for suppressing electromagnetic interference on wires and cables.

Feature Summary

• Solid construction with free-hanging installation type
• Utilizes Material 43 for effective high-frequency noise suppression
• Circular geometry optimized for cable wrapping

Applications

• Electromagnetic interference suppression on data cables
• Common mode noise reduction in electronic assemblies
• Signal integrity enhancement for high-speed interfaces

Procurement Notes

Verify the specific Material 43 designation and impedance characteristics against the official Fair-Rite datasheet to ensure compatibility with target frequency ranges. Confirm physical dimensions match the required cable outer diameter constraints. Check RoHS compliance status and packaging details directly with authorized distributors or the manufacturer prior to ordering.

Selection Notes

Select this component when a 50-ohm impedance at 100 MHz is required for EMI control. Ensure the cable diameter fits within the 4.88 mm inner diameter specification. Material 43 is appropriate for frequencies typically between 10 MHz and several hundred MHz. Compare against other Material 43 variants if different impedance values or physical sizes are needed for the specific application.

Part Context

This part belongs to the Fair-Rite 2643 series of solid ferrite cores. These components are widely used in electronics manufacturing for passive EMI filtering. The 2643375102 variant specifically offers a balance of size and impedance suitable for standard wire gauges. It is distinct from split-core designs due to its solid, non-separable construction.

Replacement Considerations

Direct substitutes include other Fair-Rite Material 43 solid cores with similar impedance and dimensional profiles, such as part numbers 2643012702 or 2643540302, provided their impedance values and physical sizes align with the design requirements.
