2867000302

Overview

The Fair-Rite 2867000302 is a multi-aperture binocular ferrite core constructed from Material 67. It features two circular apertures with an inner diameter of 0.150 inches (3.80mm) and an outer diameter of 0.295 inches (7.50mm). The component measures 13.34mm in length and has a permeability (µi) of 40. Designed for free-hanging installation, it serves as a filter for EMI/RFI suppression and inductive applications below 80 MHz.

Feature Summary

• Binocular dual-aperture geometry for balanced line filtering
• Material 67 composition optimized for low-frequency noise suppression
• Free-hanging design allows flexible cable routing

Applications

• EMI/RFI suppression on differential signal lines
• Common mode choke implementation for data cables
• Inductive circuit components operating below 80 MHz

Procurement Notes

Verify the specific material designation matches project requirements, as Ferrite compositions vary significantly by frequency response. Confirm aperture dimensions align with target cable diameters to ensure proper fit without excessive strain. Check RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when dual-channel noise reduction is required on parallel conductors. Material 67 provides high impedance at lower frequencies compared to standard mixtures. Ensure the physical size accommodates the available space within the enclosure while maintaining adequate clearance for connected cables.

Part Context

This part belongs to Fair-Rite's binocular core series, distinct from single-hole toroids or snap-on clamps. The multi-aperture design facilitates simultaneous processing of paired wires, making it suitable for balanced transmission lines where common-mode interference needs attenuation across both conductors simultaneously.

Replacement Considerations

Direct substitutes include other Fair-Rite binocular cores such as 2867000301 or 2867000303, which share similar geometries but may differ in material properties or aperture sizes. Verify dimensional compatibility before swapping to maintain mechanical integrity.
