Overview
The Fair-Rite 2843009902 is a multi-aperture ferrite core utilizing Material 43. It features three circular apertures, each with a diameter of 14.25 mm. The component has an outer diameter of 28.7 mm and an overall length of 28.7 mm. This geometry allows for the simultaneous passage of multiple conductors through a single suppression point.
Feature Summary
- Multi-aperture design enabling simultaneous cable routing
- Material 43 composition for broadband noise attenuation
- Burnished surface finish for consistent mechanical fit
Applications
- EMI suppression in multi-conductor cable assemblies
- RFI filtering for parallel signal lines
- Transformer applications requiring multi-winding configurations
Procurement Notes
Verify the specific aperture count and material designation against the manufacturer's official datasheet before integration. Confirm that the burnished finish meets your mechanical tolerance requirements. Ensure the selected variant matches the required impedance characteristics for your target frequency range.
Selection Notes
Select this component when multiple cables require common-mode noise reduction within a confined space. The Material 43 formulation provides effective attenuation across a broad frequency spectrum. Evaluate the physical dimensions to ensure compatibility with existing harness layouts and connector spacing constraints.
Part Context
This part belongs to the Fair-Rite 28 series of multi-aperture cores. These components are engineered for high-density EMI suppression tasks where standard single-hole toroids cannot accommodate multiple wires. They serve as critical passive elements in maintaining signal integrity in complex electronic systems.
Replacement Considerations
Consult Fair-Rite documentation for direct substitutes with identical aperture geometry and material properties. Verify dimensional compatibility if considering alternative manufacturers. Ensure any replacement maintains the same Material 43 specification for equivalent magnetic performance.
