2861010002

Overview

The Fair-Rite 2861010002 is a multi-aperture ferrite core constructed from Material 61. It features multiple internal apertures designed for suppressing electromagnetic interference on cables or wires. The component has an external length of approximately 30.20 mm and a width of 28.70 mm, with a height of 15.00 mm. It provides an impedance of 625 ohms at 250 MHz. The core is RoHS compliant and operates without a specified gap.

Feature Summary

• Multi-aperture design allows simultaneous processing of multiple conductors
• Material 61 composition optimized for high-frequency noise suppression
• Solid construction suitable for broadband transformer applications

Applications

• Electromagnetic interference suppression in cable assemblies
• Balun (balance-unbalance) transformer construction
• Broadband transformer implementation

Procurement Notes

Verify the specific Material 61 designation and multi-aperture geometry against the official Fair-Rite datasheet to ensure compatibility with high-frequency suppression requirements. Confirm that the physical dimensions match the intended cable bundle size. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when multi-conductor noise suppression is required in a compact footprint. Material 61 offers high permeability suitable for frequencies above 100 MHz. Ensure the aperture sizes accommodate the target cables without excessive clearance that could reduce suppression effectiveness.

Part Context

This part belongs to Fair-Rite's Multi-Aperture cores series, which are engineered for complex cable management and EMI reduction. Unlike single-hole rings, these cores integrate multiple channels into one unit, simplifying assembly while maintaining effective common-mode choke performance across a broad frequency range.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific multi-aperture configuration. Alternative solutions may require custom ordering or redesigning the cable harness to fit standard single-aperture cores.
