2743004112

Overview

The Fair-Rite 2743004112 is a ferrite core assembly designed for electromagnetic interference suppression. It features a split-core construction made from material 43, which provides high permeability and effective attenuation in the frequency range of 1 to 100 MHz. The component includes an integrated cable clamp mechanism that allows for installation around existing cables without disconnecting them. This design facilitates rapid deployment in noise reduction applications where space constraints or permanent modification are not feasible.

Feature Summary

• Split-core design enables installation on terminated cables
• Material 43 composition offers high magnetic permeability
• Integrated clamp structure secures the core around conductors

Applications

• Suppression of common-mode noise on data cables
• EMI mitigation in computer peripheral connections
• Noise filtering on power supply lines in electronic equipment

Procurement Notes

Verify the specific material grade and physical dimensions against the official Fair-Rite datasheet before procurement. Ensure the inner diameter accommodates the target cable bundle size. Confirm that the clamping force is sufficient for the intended mechanical environment. Cross-reference the part number with the manufacturer's current product listing to ensure availability and correct revision status.

Selection Notes

Select this component when non-invasive installation is required for noise suppression. Material 43 is suitable for frequencies between 1 and 100 MHz. Evaluate the cable diameter to ensure proper fit within the split core aperture. Consider the thermal environment as ferrite properties vary with temperature. Verify that the clamp mechanism meets the mechanical retention requirements of the application.

Part Context

This part belongs to the Fair-Rite ferrite core family, specifically engineered for EMI suppression. It utilizes manganese-zinc ferrite technology optimized for mid-frequency noise reduction. The split-core variant addresses the need for retrofitting noise filters onto existing wiring harnesses. It complements solid core options by providing flexibility in installation scenarios.

Replacement Considerations

Consult Fair-Rite documentation for direct equivalents. Alternative materials may offer different frequency characteristics. Ensure substitute parts match the physical dimensions and clamping mechanism. Verify compatibility with the target cable diameter and insulation type.
