2643801402

Overview

Fair-Rite 2643801402 is a solid, round ferrite cable core utilizing Material 43. It provides an impedance of 55 ohms at 100 MHz. The component features a free-hanging design with an inner diameter of 15.49 mm (0.610 inches), an outer diameter of 25.40 mm (1.000 inch), and a length of 8.13 mm (0.320 inch). It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Solid round construction for uniform magnetic properties
• Material 43 composition optimized for high-frequency noise suppression
• Free-hanging mounting style allows easy installation on cables

Applications

• EMI suppression on power and signal cables
• Common mode choke applications in electronic assemblies
• Noise filtering in industrial equipment wiring

Procurement Notes

Verify the specific impedance value and material designation against the manufacturer's current datasheet before integration. Confirm that the physical dimensions match the cable bundle size requirements. Ensure compliance with RoHS standards if required by the end application specifications.

Selection Notes

Select this part when a moderate impedance level is sufficient for noise reduction. The large inner diameter accommodates thick cables or multiple bundled wires. Material 43 is suitable for frequencies typically above 10 MHz where permeability decreases.

Part Context

This component belongs to Fair-Rite's standard line of round ferrite cores. It is distinct from split-core variants which allow installation after cable termination. The solid design ensures consistent magnetic coupling around the conductor.

Replacement Considerations

Check Fair-Rite documentation for direct substitutes with identical impedance and dimensional tolerances. Alternative materials may offer different frequency characteristics but will alter circuit performance.
