2861000102

Overview

The Fair-Rite 2861000102 is a multi-aperture ferrite core utilizing Material 61, characterized by a high initial permeability of 125. This component features two distinct apertures designed for simultaneous cable passage or balanced line integration. It exhibits an impedance of 160 ohms at 100 MHz, providing effective attenuation for high-frequency noise. The solid construction ensures mechanical stability without requiring external mounting hardware.

Feature Summary

• Dual-aperture geometry facilitates the routing of multiple conductors or balanced pairs through a single suppression point.
• Material 61 composition offers high magnetic permeability suitable for broadband interference suppression applications.
• Solid cylindrical design provides structural integrity and consistent magnetic coupling around enclosed cables.

Applications

• Electromagnetic interference (EMI) suppression on differential signal lines
• Common mode choke implementation for balanced audio or data interfaces
• Noise filtering in mixed-signal circuit board cabling

Procurement Notes

Verify that the specific order matches the manufacturer part number 2861000102 to ensure receipt of the dual-aperture variant rather than single-hole alternatives. Confirm compliance with current RoHS directives as indicated in official documentation. Request the latest datasheet to validate material specifications before finalizing procurement for sensitive RF environments.

Selection Notes

Select this component when dual-cable management within a single suppression zone is required. The Material 61 selection prioritizes permeability over saturation characteristics, making it ideal for low-current signal lines rather than power transmission. Ensure the inner diameter accommodates the target cable bundle diameter without excessive strain during installation.

Part Context

This part belongs to Fair-Rite's multi-aperture ferrite series, specifically engineered for complex cabling scenarios. Unlike standard toroids, the dual-hole design allows for integrated balancing or simultaneous grounding of adjacent wires. It serves as a specialized passive component within broader EMI mitigation strategies for electronic assemblies.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific dual-aperture configuration. Alternative solutions may require custom ordering or redesigning the layout to accommodate separate single-aperture cores if exact dimensional and electrical matching is critical.
