2873000202

Overview

Fair-Rite 2873000202 is a multi-aperture ferrite core utilizing Material 73 with an initial permeability of 2500. It features a binocular design with dimensions of 14.35 mm length, 7.5 mm width, and 13.3 mm height. The component provides an impedance of 125 ohms at 10 MHz and has a minimum inductance factor (AL) of 8500 nH.

Feature Summary

• Binocular multi-aperture geometry for enhanced magnetic coupling
• Material 73 composition optimized for high-frequency suppression
• High initial permeability for efficient noise attenuation

Applications

• Airbag circuit noise suppression to prevent accidental activation
• Common mode choke applications in automotive electronics
• EMI filtering for high-speed data lines

Procurement Notes

Verify the specific Material 73 designation and binocular aperture configuration against the manufacturer datasheet. Confirm dimensional tolerances and impedance characteristics at 10 MHz match system requirements. Ensure compliance with RoHS standards as indicated in official documentation.

Selection Notes

Select this component when high permeability and specific multi-aperture geometry are required for EMI suppression. Material 73 is suitable for frequencies where higher impedance is needed compared to standard mixtures. Verify physical clearance for the binocular shape during PCB layout.

Part Context

This part belongs to Fair-Rite's multi-aperture ferrite core series, specifically designed for applications requiring controlled magnetic coupling between multiple conductors. The binocular shape distinguishes it from standard toroidal or snap-on cores, offering unique inductive properties for differential line filtering.

Replacement Considerations

Direct substitutes must match the Material 73 specification and binocular form factor. Verify that alternative parts maintain the same AL value and impedance profile at 10 MHz to ensure equivalent performance in sensitive circuits like airbag systems.
