475184751

Overview

Fair-Rite part number 475184751 is a clip-on ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 31, which provides high impedance in the VHF and UHF frequency ranges. The component features an openable design with a single split to allow installation over existing cables without disconnection. Key physical dimensions include an inner diameter of 6.6 mm, an outer width of 20 mm, an outer height of 39.4 mm, and a depth of 9.8 mm. The material exhibits an impedance of 380 Ω at 100 MHz and 225 Ω at 25 MHz.

Feature Summary

• Openable hinged construction enables retrofitting onto terminated cables
• Material 31 composition optimized for VHF/UHF noise absorption
• Circular cross-section accommodates round cable geometries

Applications

• Electromagnetic interference suppression on data and power lines
• Retrofit noise filtering on existing cable assemblies
• Common mode choke application for signal integrity enhancement

Procurement Notes

Verify the specific Material 31 designation and dimensional tolerances against the official Fair-Rite datasheet prior to procurement. Confirm that the openable hinge mechanism meets the mechanical retention requirements of the target assembly. Ensure compliance with RoHS standards if required by the end-use environment. Cross-reference the part number with authorized distributors to confirm current manufacturing status and availability.

Selection Notes

Select this component when post-assembly installation is required due to its openable design. Material 31 is appropriate for applications targeting noise frequencies above 30 MHz. Evaluate the cable diameter to ensure it fits within the 6.6 mm inner diameter constraint. Consider the physical footprint of 20 mm x 39.4 mm for spatial clearance in the final enclosure design.

Part Context

This component belongs to the Fair-Rite Openable series of ferrite cores. These cores are distinct from solid toroids as they feature a split design secured by a hinge or clip. They are primarily used for EMI mitigation where cables cannot be disconnected during installation. The series offers various materials tailored to different frequency response profiles.

FAQ

What is the operating temperature range for Material 31?

Fair-Rite Material 31 typically operates effectively within standard commercial temperature ranges, though specific limits should be verified in the material data sheet.

Does the openable design affect the magnetic performance compared to solid cores?

The air gap introduced by the openable design may slightly reduce effective permeability compared to a solid core, but it remains effective for EMI suppression applications.
