5961001101

Overview

The Fair-Rite Products Corp. 5961001101 is a solid, free-hanging ferrite toroid core constructed from 61 material composition. It features an inner diameter of 7.9 mm (0.311 inches), an outer diameter of 12.7 mm (0.500 inches), and a height of 6.35 mm (0.250 inches). This component operates within the low-medium permeability frequency range of 200-1000 MHz. It is designed for use in closed magnetic circuits and supports applications including pulse transformers, ground fault circuit interrupters, broadband transformers, power input filters, and common mode filters.

Feature Summary

• Solid, free-hanging ring configuration suitable for closed magnetic circuits
• Operates effectively within the 200-1000 MHz frequency range

Applications

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

Procurement Notes

Verify the specific material grade and physical dimensions against project requirements before procurement. Confirm that the 61 material composition aligns with the intended operating frequency range of 200-1000 MHz. Ensure the solid, free-hanging form factor fits the mechanical constraints of the assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a low-medium permeability ferrite core is required for frequencies between 200 MHz and 1 GHz. The 61 material offers specific magnetic properties distinct from other grades like 43 or 67. Consider the physical dimensions of 7.9 mm ID and 12.7 mm OD for wire winding space. Evaluate the suitability of the solid toroid shape for the specific magnetic circuit topology.

Part Context

This part belongs to the Fair-Rite 59 series of ferrite toroids. The 59 series typically denotes standard toroidal cores available in various material compositions. The 61 material is specifically engineered for applications requiring stable inductance over a broad frequency spectrum, distinguishing it from high-permeability materials used for lower frequency noise suppression.

Replacement Considerations

Direct substitutes may include other Fair-Rite 59 series toroids with identical 7.9 mm ID, 12.7 mm OD, and 6.35 mm height dimensions but different material compositions if frequency response adjustments are permissible. Verify compatibility with existing winding forms and magnetic circuit designs when considering alternative material grades.
