2843002402

Overview

Fair-Rite 2843002402 is a multi-aperture ferrite core utilizing Material 43, designed for frequencies between 20 MHz and 300 MHz. It features an oval geometry with internal dimensions of 7 mm by 6.2 mm and an external length of 4.2 mm. The component provides an impedance of 100 ohms at a test frequency of 100 MHz. It is classified as a binocular type core suitable for EMI suppression applications.

Feature Summary

• Multi-aperture design facilitates simultaneous winding of multiple conductors within a single magnetic structure.
• Material 43 composition offers high permeability optimized for noise suppression in the VHF and UHF spectrum.

Applications

• Common mode choke implementation for data lines
• EMI suppression on high-frequency signal cables
• Filtering components in RF circuit assemblies

Procurement Notes

Verify the specific material grade and dimensional tolerances against the manufacturer datasheet prior to integration. Confirm that the multi-aperture configuration aligns with the required conductor count and spacing constraints for the target assembly design.

Selection Notes

Select this component when dual-conductor noise filtering is required within a compact footprint. The Material 43 formulation ensures effective attenuation above 20 MHz. Ensure the physical aperture size accommodates the diameter of the intended cable or wire bundle without excessive clearance.

Part Context

This part belongs to the Fair-Rite 28 series of multi-aperture cores. It serves as a specialized variant for applications requiring two distinct magnetic paths or simultaneous handling of paired signals, differing from standard single-hole toroidal designs.

Replacement Considerations

Direct substitutes include other Fair-Rite 28-series binocular cores with compatible Material 43 specifications. Verify cross-reference availability through official distributor catalogs to ensure identical electrical performance and mechanical fit.

FAQ

What is the primary function of the multi-aperture design?

The multi-aperture structure allows for the independent routing of two separate conductors through the same magnetic core, enabling common-mode noise rejection for paired lines.

At what frequency is the impedance rating specified?

The impedance rating of 100 ohms is measured at a test frequency of 100 MHz.
