2873000302

Overview

Fair-Rite 2873000302 is a multi-aperture ferrite core utilizing Material 73. It features a binocular geometry with dimensions of 13.3 mm length, 7.5 mm width, and 10.3 mm height. The component provides an impedance of 94 ohms at 10 MHz and has an initial permeability (µi) of 2500.

Feature Summary

• Multi-aperture binocular design for dual-winding applications
• Material 73 composition optimized for high-frequency noise suppression
• High initial permeability for effective common-mode choke performance

Applications

• Common-mode chokes in high-speed digital interfaces
• EMI suppression for differential signal lines
• Noise filtering in RF circuits

Procurement Notes

Verify the specific Material 73 designation and physical dimensions against the official Fair-Rite datasheet to ensure compatibility with your PCB footprint or cable assembly requirements. Confirm that the binocular aperture size accommodates your wire gauge. Check for RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when high permeability is needed for low-frequency noise attenuation combined with effective high-frequency damping. The binocular shape facilitates balanced winding for differential pairs. Ensure the operating frequency range aligns with the material's impedance characteristics for optimal EMI reduction.
