2867002402

Overview

Fair-Rite 2867002402 is a solid, free-hanging ferrite core designed for cable electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing an impedance of 100 Ohms at 100 MHz. The component features a circular design with an inner diameter of 0.067 inches (1.70 mm), an outer diameter of 0.165 inches (4.20 mm), and a length of 0.244 inches (6.20 mm).

Feature Summary

• Solid construction eliminates the need for assembly tools or clips.
• Material 43 composition provides high permeability for effective noise absorption.
• Free-hanging design allows for easy installation on existing cables.

Applications

• Suppression of common-mode noise on small-diameter signal cables.
• EMI filtering in compact electronic assemblies.
• Noise reduction on data lines and sensor wiring.

Procurement Notes

Verify the specific impedance requirement against the application frequency spectrum before ordering. Confirm that the cable diameter falls within the 1.70 mm inner diameter tolerance to ensure a secure fit without excessive force. Check RoHS compliance status if required by the end-product regulations.

Selection Notes

Select this part when space constraints prevent the use of split cores or snap-on beads. Material 43 is optimal for frequencies between 10 MHz and 100 MHz. Ensure the current rating of the cable does not exceed thermal limits, although ferrite cores primarily affect impedance rather than carrying current themselves.

Part Context

This component belongs to the Fair-Rite solid ferrite core family, specifically engineered for direct cable insertion. It serves as a passive filter element in EMI mitigation strategies, distinct from split-core variants which require mechanical opening for installation.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Alternative selection requires matching Material 43 specifications, impedance curves, and physical dimensions.
