2843010302

Overview

Fair-Rite 2843010302 is a multi-aperture ferrite core utilizing Material 43. It features an inner diameter of 4.75 mm and an outer diameter of 9.50 mm, with a length of 19.43 mm. The component provides an impedance of 295 ohms at 25 MHz and 475 ohms at 100 MHz. Designed for suppression applications, it supports multiple cable passes through its apertures to enhance common-mode noise attenuation in broadband transformers and baluns.

Feature Summary

• Multi-aperture design enables multiple cable passes for enhanced suppression
• Material 43 composition optimized for high-frequency noise attenuation
• Free-hanging form factor suitable for integration into various assemblies

Applications

• Balun construction
• Broadband transformer cores
• Airbag circuit suppression

Procurement Notes

Verify the specific impedance requirements against the application frequency. Confirm that the inner diameter accommodates the target cable bundle. Ensure compliance with RoHS standards if required by the end product specifications.

Selection Notes

Select this part when multiple conductor passes are necessary within a confined space. Material 43 offers a balanced permeability for general-purpose EMI suppression. Compare dimensions against available mounting space before finalizing the design.

Part Context

This component belongs to Fair-Rite's 28 series of multi-aperture cores. These cores are distinct from standard toroids due to their internal geometry, which allows for higher effective turns per pass without increasing the overall footprint significantly.

Replacement Considerations

No public confirmed substitute part numbers are available.
