5977006401

Overview

Fair-Rite Products Corp. part number 5977006401 is a ferrite toroid core manufactured from Material 77. This component is designed for electromagnetic interference suppression and high-frequency applications. The core features a toroidal geometry suitable for winding inductors or transformers. It is RoHS compliant and classified under ECCN EAR99. The standard lead time for this item is typically between 15 to 17 weeks.

Feature Summary

• Manufactured using Fair-Rite Material 77 for specific high-frequency magnetic properties
• Toroidal shape provides closed magnetic path with minimal external flux leakage
• RoHS compliant construction meeting environmental standards

Applications

• High-frequency transformer cores
• Inductor windings for RF circuits
• Electromagnetic interference suppression components

Procurement Notes

Verify the exact material grade is 77, as this determines the permeability and loss characteristics. Confirm the physical dimensions against your winding requirements. Check the current standard lead time, which varies by distributor between 15 and 17 weeks. Ensure the packaging type matches your assembly line needs, as sources indicate reel packaging options may be available.

Selection Notes

Select this part when Material 77's specific permeability and low-loss characteristics at high frequencies are required. Compare the inner diameter and outer diameter against your wire gauge and space constraints. Consider that Material 77 differs significantly from common Materials like 43 or 61, so substitute parts must match the material grade, not just the physical size.

Part Context

This component belongs to the Fair-Rite Ferrite Toroids product category. It is distinct from snap-on or solid rod ferrites due to its ring shape, which allows for uniform winding distribution. Material 77 is optimized for different frequency ranges compared to other Fair-Rite materials, making it suitable for specialized RF and power conversion designs.

Replacement Considerations

Direct substitutes must use Material 77. Physical dimensions (inner/outer diameter, height) must match exactly. Generic ferrite rings are not acceptable replacements due to varying magnetic properties.
