5977001101

Overview

The Fair-Rite 5977001101 is a solid, free-hanging ferrite toroid core manufactured from Material 77. It features an inner diameter of 7.9 mm (0.311 inches), an outer diameter of 12.7 mm (0.500 inches), and a length of 6.35 mm (0.250 inches). The component operates within a temperature range of -55°C to +90°C and provides an inductance factor of 1.3 µH.

Feature Summary

• Utilizes Material 77 composition for high permeability and effective noise suppression across broad frequency ranges.
• Solid toroidal geometry designed for free-hanging installation on cables without requiring mounting hardware.
• Engineered to function reliably within extreme environmental temperatures ranging from -55°C to +90°C.

Applications

• Electromagnetic interference suppression on data and power cables
• Common mode choke implementation in signal lines
• Noise filtering in broadband transformer windings

Procurement Notes

Verify the specific Material 77 designation against project requirements to ensure compatibility with target frequency spectra. Confirm that the solid toroidal dimensions align with cable bundle diameters. Check RoHS compliance status if restricted substances are mandated by regional regulations.

Selection Notes

Select this component when high permeability is required for low-frequency noise attenuation. Ensure the cable diameter fits within the 7.9 mm inner bore. Consider thermal constraints as the operating limit extends to 90°C. Evaluate if the solid design suits the mechanical routing environment compared to hinged alternatives.

Part Context

This part belongs to the Fair-Rite solid ferrite core family, distinguished by its fixed toroidal shape. It differs from split-core variants by requiring cable threading during assembly. Material 77 offers distinct magnetic properties optimized for general-purpose EMI suppression compared to other material compositions in the catalog.

Replacement Considerations

Substitute parts must match the 7.9 mm ID, 12.7 mm OD, and 6.35 mm length. Verify equivalent Material 77 composition for identical magnetic performance. Ensure the replacement maintains the solid toroidal form factor for compatible mechanical integration.
