2861001702

Overview

Fair-Rite Products Corp. part number 2861001702 is a multi-aperture ferrite core constructed from Material 61. This component features multiple apertures designed to accommodate several conductors simultaneously, providing enhanced electromagnetic interference suppression capabilities in compact spaces. The core utilizes the specific magnetic properties of Material 61, which offers high permeability and low losses at frequencies typically ranging from 1 MHz to 100 MHz. It is classified as a cable ferrite intended for free-hanging installation without mechanical fasteners.

Feature Summary

• Multi-aperture design allows simultaneous passage of multiple cables through a single suppressor unit
• Utilizes Material 61 composition optimized for high-frequency noise attenuation
• Free-hanging installation style eliminates need for mounting hardware or brackets

Applications

• Suppression of common-mode noise on multi-conductor data cables
• EMI filtering in telecommunications equipment signal lines
• Noise reduction in automotive wiring harnesses with bundled conductors

Procurement Notes

Verify the exact aperture count and internal dimensions against the official Fair-Rite datasheet before integration, as multi-aperture cores vary significantly in physical layout. Confirm that Material 61 aligns with your target frequency range requirements. Ensure the supplier provides RoHS compliance documentation consistent with current manufacturing standards.

Selection Notes

Select this component when space constraints prevent the use of multiple single-aperture cores. Material 61 is suitable for applications requiring effective noise suppression in the medium-to-high frequency range. Compare the total impedance contribution of all apertures against the source impedance of the noise to ensure adequate attenuation performance.

Part Context

This part belongs to the Fair-Rite multi-aperture ferrite core family, distinct from solid or hinged single-aperture designs. These cores are engineered for scenarios where multiple wires must be bundled and filtered together. The designation indicates a specific configuration within the broader catalog of cable ferrites offered by the manufacturer.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with existing assembly fixtures due to potential dimensional differences in multi-aperture layouts.
