2843003102

Overview

Fair-Rite 2843003102 is a multi-aperture ferrite toroid core manufactured from Material 43. It features five circular apertures, each with an inner diameter of 1.8 mm and an outer length of 4.2 mm. The core has an external width of 6.2 mm. It provides an impedance of 100 ohms at a test frequency of 100 MHz, operating within a frequency range of 20 MHz to 300 MHz. The unit weighs approximately 18 grams.

Feature Summary

• Multi-aperture design accommodating multiple conductors simultaneously
• Material 43 composition optimized for high-frequency noise suppression
• Compact oval geometry suitable for dense wiring harnesses

Applications

• Electromagnetic interference suppression in multi-conductor cables
• Common mode choke applications for data lines
• High-frequency noise filtering in electronic assemblies

Procurement Notes

Verify the specific material grade and dimensional tolerances against the official Fair-Rite datasheet before integration. Confirm that the multi-aperture configuration matches the cable bundle diameter requirements. Ensure compliance with relevant environmental regulations such as RoHS standards applicable to your region.

Selection Notes

Select this component when simultaneous suppression of multiple wires is required within a confined space. The Material 43 formulation is appropriate for frequencies between 20 MHz and 300 MHz. Evaluate the 1.8 mm aperture size against the total cross-section of the cables to ensure proper fit without excessive strain.

Part Context

This part belongs to the Fair-Rite 28 series of ferrite toroids. These components are designed for EMI suppression in electronic circuits. The multi-aperture variant allows for the processing of several wires through a single magnetic structure, simplifying assembly compared to individual cores.

Replacement Considerations

Direct substitutes must match the five-aperture geometry, Material 43 composition, and similar impedance characteristics. Verify dimensional compatibility with existing cable bundles. Consult Fair-Rite documentation for equivalent parts with identical electrical performance.
