2643814002

Overview

Fair-Rite Products Corp. part number 2643814002 is a solid, free-hanging ferrite core designed for cable filtering applications. It utilizes Fair-Rite Material 43 and provides an impedance of 169 ohms at 100 MHz. The component features a round design with an inner diameter of 7.62 mm (0.300 inches), an outer diameter of 15.88 mm (0.625 inches), and a length of 25.4 mm (1.000 inch).

Feature Summary

• Solid construction made from Material 43 for effective high-frequency noise suppression.
• Free-hanging installation type allows for easy placement on cables without mounting hardware.
• Round geometry supports uniform magnetic flux distribution around the conductor.

Applications

• Electromagnetic interference (EMI) suppression on data cables
• Common mode choke implementation for signal lines
• Noise reduction in industrial control wiring

Procurement Notes

Verify the specific impedance requirement matches the application frequency spectrum, as Material 43 characteristics vary across bands. Confirm physical dimensions align with available cable clearance. Check RoHS compliance status if required by project specifications. Ensure ordering quantities match distributor packaging standards to avoid partial reel issues.

Selection Notes

Select this component when a solid, non-split core is preferred over openable types for permanent installations. Material 43 offers a balanced permeability suitable for general-purpose EMI suppression in the VHF range. Compare inner diameter constraints against target cable bundles to ensure proper fit without excessive strain.

Part Context

This part belongs to Fair-Rite's standard line of solid ferrite cores, distinct from their split or snap-on varieties. It is categorized under cable ferrites intended for direct wire wrapping. The product line emphasizes consistent material properties for predictable filtering performance in electronic assemblies.

Replacement Considerations

Direct substitutes include other Material 43 solid cores with matching 7.62 mm inner diameter and similar impedance profiles. Verify that alternative manufacturers' Material 43 equivalents meet the same impedance tolerance and temperature stability requirements.
