5977000301

Overview

The Fair-Rite 5977000301 is a solid, free-hanging ferrite core toroid constructed from Material 77. It features an inner diameter of 0.311 inches (7.90mm), an outer diameter of 0.500 inches (12.70mm), and a length of 0.193 inches (4.90mm). This component is designed for cable ferrite applications to suppress electromagnetic interference.

Feature Summary

• Solid toroidal geometry for uniform magnetic circuit performance
• Material 77 composition optimized for high-frequency noise suppression
• Free-hanging installation design for flexible cable integration

Applications

• Power supply filtering
• Battery charger EMI reduction
• Portable device signal integrity enhancement

Procurement Notes

Verify the specific material grade and physical dimensions against official Fair-Rite datasheets before procurement. Confirm that the Material 77 specification aligns with the target frequency range of the application. Ensure the free-hanging form factor is compatible with the intended cable assembly constraints.

Selection Notes

Select this component when high-frequency attenuation is required using Material 77 properties. The solid toroid shape provides consistent inductance characteristics. Verify that the internal bore size accommodates the target cable diameter without excessive clearance or tight fit issues during installation.

Part Context

This part belongs to the Fair-Rite Cable Ferrites category, specifically within the Toroids product line. It utilizes Material 77, which is distinct from other grades like Material 68 or 75, offering specific permeability characteristics suitable for its designated noise suppression frequencies.
