2861002702

Overview

Fair-Rite 2861002702 is a solid, free-hanging ferrite core utilizing Material 61 (Ni-Zn). It features an inner diameter of 0.067 inches (1.70mm), an outer diameter of 0.165 inches (4.20mm), and a length of 7.01mm. The component provides an impedance of 45 Ohms at 100MHz. Designed for cable ferrite applications, it supports suppression functions and balun configurations.

Feature Summary

• Solid construction with free-hanging design for easy installation on cables
• Utilizes Nickel-Zinc (Ni-Zn) Material 61 for high-frequency performance
• Optimized for electromagnetic interference suppression and balance-unbalance transformation

Applications

• Electromagnetic interference suppression on small cables
• Balun (balance-unbalance) transformer cores
• High-frequency signal line filtering

Procurement Notes

Verify the specific material composition and impedance characteristics against your frequency requirements. Confirm that the inner diameter accommodates the target cable size. Ensure compliance with relevant environmental standards such as RoHS if applicable to your manufacturing process.

Selection Notes

Select this component when a compact, solid ferrite core is required for high-frequency noise reduction. Material 61 is suitable for frequencies typically above 10MHz. Ensure the physical dimensions fit within the available space constraints of the assembly.

Part Context

This part belongs to Fair-Rite's cable ferrite product line, specifically designed for suppressing common-mode noise on wires and cables. The solid design distinguishes it from split-core alternatives, offering a permanent magnetic path once installed.

Replacement Considerations

Check for equivalent parts using Material 61 with similar impedance curves. Verify dimensional compatibility, particularly the inner diameter and overall length, to ensure proper fit on the intended cable.
