5961000301

Overview

The Fair-Rite 5961000301 is a ferrite toroidal core manufactured from Material 61. It features an outer diameter of 12.7 mm, an inner diameter of 7.15 mm, and a height of 4.9 mm. The component exhibits an inductance of 69 nH at a test frequency of 10 kHz. It operates within a temperature range of -55°C to +90°C and complies with RoHS standards.

Feature Summary

• Utilizes Material 61 composition for high-frequency performance
• Toroidal geometry provides efficient magnetic flux containment
• Designed for broadband transformer applications

Applications

• Broadband transformers
• Pulse transformers
• Ground fault circuit interrupters
• Power supply input filters
• Common mode filters

Procurement Notes

Verify the specific Material 61 designation and physical dimensions against official Fair-Rite datasheets before integration. Confirm that the operating temperature range of -55°C to +90°C aligns with the target environment. Ensure compliance with RoHS directives if required by the final product specifications.

Selection Notes

Select this component when high permeability and broad bandwidth are required for signal integrity. Material 61 is optimized for frequencies where standard materials may exhibit excessive losses. Consider the T13/7.2/4.8 size constraints for PCB or chassis mounting space limitations.

Part Context

This part belongs to the Fair-Rite 59 series of ferrite rings. It is distinct from solid cable cores like the 2643 series due to its open-loop toroidal design intended for winding custom coils rather than clamping over existing cables.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
