2861006802

Overview

The Fair-Rite Products Corp. 2861006802 is a multi-aperture ferrite core constructed from Material 61 (NiZn). It features a solid design with an impedance of 510 Ohms at 100 MHz and an inductance factor (AL value) of 600 nH. The component operates within a temperature range of -55°C to +125°C. Its physical dimensions include a length of 13.34 mm, designed for mounting on round cables.

Feature Summary

• Multi-aperture geometry for enhanced magnetic coupling
• Material 61 composition controlled for both impedance and AL value
• Solid construction suitable for broadband applications

Applications

• Signal suppression
• Balun implementations
• Broadband transformer cores

Procurement Notes

Verify the specific material designation upon ordering, as sources indicate potential variations between Material 61 and Material 67 for this part number. Confirm that the required specifications align with Material 61 characteristics, which are controlled for both impedance and AL value, rather than impedance-only control found in other materials like 73 or 43.

Selection Notes

Select this component when precise control over both impedance and inductance factor is required for NiZn applications. The multi-aperture design facilitates efficient winding for transformer or balun uses. Ensure the operating frequency range around 100 MHz matches the 510 Ohm impedance profile provided by Material 61.

Part Context

This component belongs to Fair-Rite's cable ferrite series, specifically utilizing multi-aperture technology. Unlike standard snap-on cores, these allow for controlled winding turns, making them distinct from simple suppression beads. They are engineered for consistent performance in electromagnetic interference mitigation circuits.

Replacement Considerations

Direct substitutes require matching Material 61 properties and multi-aperture geometry. Generic ferrite cores may lack the specific AL value control necessary for transformer applications.
