5975000301

Overview

The Fair-Rite Products Corp. part number 5975000301 is a solid free-hanging ferrite toroid core belonging to the 59x series. It utilizes Material 75, characterized by high permeability suitable for common-mode noise suppression. The component features an inner diameter of 0.281 inches (7.15 mm), an outer diameter of 0.500 inches (12.70 mm), and a length of 0.193 inches (4.90 mm). This specific geometry and material combination provides effective electromagnetic interference filtering for power input circuits and ground-fault interrupters.

Feature Summary

• High permeability Material 75 composition optimized for common-mode noise attenuation
• Solid free-hanging toroidal design with burnished edges for safe handling
• Compact form factor suitable for winding directly onto cables or leads

Applications

• Power input filter circuits
• Ground-fault interrupter assemblies
• Common-mode choke implementation

Procurement Notes

Verify the specific lot date code upon receipt to ensure compliance with current manufacturing standards. Confirm that the received components match the physical dimensions and material grade specified in the official datasheet. Check for any shipping damage to the burnished surfaces which could affect installation integrity in sensitive applications.

Selection Notes

Select this component when high permeability is required for low-frequency common-mode noise suppression. The Material 75 specification distinguishes it from lower permeability alternatives like Material 43. Ensure the cable or wire bundle fits within the 7.15 mm inner diameter without excessive force that might crack the ceramic core during installation.

Part Context

This part belongs to the Fair-Rite 59x Toroid series, where the prefix indicates the product class and the subsequent digits define the material grade and dimensions. Material 75 is specifically engineered for applications requiring significant impedance at lower frequencies compared to other ferrite materials in the manufacturer's portfolio.

Replacement Considerations

Direct substitutes include other manufacturers' T12.7/7.15/4.90 dimension toroids using Material 75 equivalents. Verify that alternative sources maintain the same permeability characteristics and physical tolerances to ensure identical circuit performance.
