2843000202

Overview

The Fair-Rite 2843000202 is a multi-aperture ferrite suppression core constructed from Material 43. Designed for round cables, this cylindrical component features an internal diameter of 5.1 mm and external dimensions of 12.8 mm by 25 mm with a depth of 5.6 mm. It exhibits an impedance of 100 Ω at 100 MHz and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multi-aperture geometry designed for suppressing electromagnetic interference on round cables
• Utilizes Material 43 composition for effective noise attenuation in the specified frequency range
• Cylindrical form factor suitable for integration into compact electronic assemblies

Applications

• Airbag system designs to prevent accidental activation
• Electromagnetic interference suppression on wiring harnesses
• Signal integrity enhancement in automotive electronics

Procurement Notes

Verify that the specific application requires Material 43 characteristics rather than alternative compositions. Confirm that the cable diameter falls within the 5.1 mm aperture limit to ensure proper fit. Check for RoHS compliance requirements if the end product mandates specific environmental standards. Ensure the operating temperature range of -55°C to +125°C meets the environmental conditions of the installation site.

Selection Notes

Select this component when high-frequency noise suppression is required on round cables within automotive or industrial environments. The Material 43 composition offers a balanced permeability and resistivity profile suitable for broadband interference reduction. Consider the physical dimensions to ensure adequate clearance within the assembly housing. Evaluate the impedance curve at the target frequency to confirm sufficient attenuation performance for the specific noise spectrum encountered.

Part Context

This part belongs to the Fair-Rite multi-aperture core series, which provides specialized geometries for cable management and noise control. Material 43 is a widely used ferrite formulation known for its effectiveness in the VHF and UHF ranges. The multi-aperture design allows multiple conductors to pass through while maintaining magnetic coupling for common-mode noise suppression.

Replacement Considerations

BN-43-202 is a documented substitute part number offering equivalent Material 43 properties and similar dimensional specifications.
