2843002702

Overview

Fair-Rite 2843002702 is a solid free-hanging ferrite core belonging to the multi-aperture series. It utilizes material 43 and provides an impedance of 64 Ohms at 100 MHz. The component features a circular cross-section with an inner diameter of 0.067 inches (1.70 mm), an outer diameter of 0.165 inches (4.20 mm), and a length of 7.01 mm.

Feature Summary

• Multi-aperture design for distributing magnetic flux across multiple conductors
• Material 43 composition optimized for noise suppression in the high-frequency range
• Solid construction suitable for free-hanging installation on cables

Applications

• Electromagnetic interference suppression on data cables
• Common mode noise reduction on power lines
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific impedance requirement against the application frequency, as Material 43 characteristics vary significantly across the spectrum. Confirm that the cable bundle diameter fits within the 1.70 mm inner diameter specification. Ensure the mounting environment accommodates the free-hanging form factor without mechanical stress on the connected wires.

Selection Notes

Select this part when multi-conductor noise suppression is required within a compact footprint. The 1.70 mm aperture limits usage to smaller gauge cables or tightly bundled wires. Compare against single-aperture cores if higher individual conductor impedance is needed, or consider larger aperture variants for thicker cable bundles.

Part Context

This component is part of Fair-Rite's extensive line of ferrite materials and cores. Material 43 is widely used for broadband noise suppression applications. The multi-aperture geometry allows for efficient coupling with multiple parallel traces or wires, making it distinct from standard single-hole toroids.

Replacement Considerations

Direct substitutes include other Fair-Rite multi-aperture cores using Material 43, such as 2843002302, provided the physical dimensions and impedance profiles match the design constraints.
