431176451

Overview

Fair-Rite Products Corp. part number 431176451 is a hinged ferrite core designed for electromagnetic interference suppression. It features a circular snap-bead assembly with an internal diameter of 18.34 mm. The component utilizes Fair-Rite Material 43, providing an impedance of 380 ohms at 100 MHz. It is classified as a cable ferrite bead suitable for free-hanging installation.

Feature Summary

• Hinged design allows for easy installation around existing cables without disconnection
• Utilizes Material 43 composition for high-frequency noise attenuation
• Circular snap-bead form factor provides controlled impedance characteristics

Applications

• Electromagnetic interference suppression on cables
• High-frequency noise filtering in electronic assemblies

Procurement Notes

Verify the specific impedance tolerance and material grade against the official Fair-Rite datasheet before procurement. Confirm that the hinged mechanism meets the mechanical requirements for the intended cable bundle size. Ensure compliance with RoHS standards if required by the end application specifications.

Selection Notes

Select this component when retrofitting ferrite suppression onto existing wiring harnesses where opening the loop is not feasible. The 18.34 mm inner diameter accommodates specific cable gauges. Material 43 is appropriate for applications requiring significant attenuation in the upper frequency range compared to lower permeability materials.

Part Context

This part belongs to the Fair-Rite Snap-It series of cable ferrites. These assemblies are distinct from solid cores due to their hinged construction, facilitating field installation. The product line focuses on providing controlled impedance solutions for common mode noise reduction in various electronic environments.
