2843000302

Overview

The Fair-Rite 2843000302 is a multi-aperture ferrite suppression core constructed from Material 43. It features an external height of 13.3 mm and provides an impedance of 130 Ohms within the frequency range of 20 MHz to 300 MHz. Designed for broadband suppression applications, this cylindrical component serves as an effective electromagnetic interference filter for cable assemblies.

Feature Summary

• Multi-aperture design for enhanced magnetic coupling
• Material 43 composition for broadband noise suppression
• Cylindrical form factor suitable for various cable diameters

Applications

• Airbag system circuit protection
• Broadband electromagnetic interference suppression
• Cable assembly noise filtering

Procurement Notes

Verify the specific impedance value against the latest manufacturer datasheet, as sources indicate variations between 100 and 130 Ohms at different frequencies. Confirm that the Material 43 specification aligns with your target frequency requirements. Ensure the physical dimensions match your cable clearance constraints before finalizing procurement orders.

Selection Notes

Select this component when broadband suppression is required across the 20 MHz to 300 MHz spectrum. The multi-aperture structure allows for multiple wire passes to increase attenuation. Material 43 offers high permeability suitable for lower frequency noise compared to higher-numbered materials. Evaluate the 13.3 mm height to ensure adequate space in the assembly.

Part Context

This part belongs to the Fair-Rite 2843 series of multi-hole cores. These components are specifically engineered for suppressing common-mode noise on cables. The series utilizes various ferrite materials to optimize performance across different frequency bands, with Material 43 being a standard choice for general-purpose broadband applications.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing designs if considering alternative multi-aperture cores from other manufacturers.
