2843001802

Overview

Fair-Rite 2843001802 is a solid multi-aperture ferrite core utilizing Material 43. It features an inner diameter of 1.1 mm and an outer diameter of 6.4 mm with a length of 6.35 mm. The component provides an impedance of 166 ohms at 100 MHz. Designed for free-hanging cable applications, it serves as a compact electromagnetic interference suppression solution.

Feature Summary

• Solid multi-aperture construction for direct cable insertion
• Material 43 composition optimized for high-frequency noise absorption
• Compact physical dimensions suitable for tight spatial constraints

Applications

• Electromagnetic interference suppression on small gauge cables
• Common mode choke implementation in signal lines
• High-frequency noise filtering in electronic assemblies

Procurement Notes

Verify the specific Material 43 designation and impedance tolerance against the manufacturer's current datasheet before integration. Confirm that the 1.1 mm inner diameter accommodates the target cable insulation thickness without mechanical stress. Ensure compliance with RoHS standards if required by the end product specifications.

Selection Notes

Select this component when a solid, non-split ferrite design is preferred over clamshell types for permanent installation. Material 43 is appropriate for frequencies between 10 MHz and several hundred MHz. Evaluate the 166 ohm impedance value to ensure it matches the system's noise frequency profile and attenuation requirements.

Part Context

This part belongs to Fair-Rite's 28 series of multi-aperture cores. These components are distinct from split cores as they require threading cables through the center during assembly. They are widely used in telecommunications and computing industries for EMI control where space is limited.

Replacement Considerations

Direct substitutes include other Material 43 solid cores with similar dimensions, such as Fair-Rite 2843002402 or 2843010302, provided the inner diameter and impedance characteristics align with the original design requirements.
