444173951

Overview

Fair-Rite 444173951 is a split core ferrite assembly designed for electromagnetic interference suppression. It features a circular cable embedded design with an internal diameter of 5.1 mm (0.201 inches). The component provides an impedance of 150 Ohms at 100 MHz and 110 Ohms at 25 MHz. Physical dimensions include an external width of 12.8 mm (0.504 inches) and height of 5.6 mm (0.220 inches). It utilizes Fair-Rite Material 43 and complies with RoHS standards.

Feature Summary

• Hinged snap-on construction allows installation around existing cables without disconnection
• Utilizes Material 43 composition for effective high-frequency noise attenuation
• Free-hanging design facilitates flexible mounting in various configurations

Applications

• Electromagnetic interference suppression on round cables
• High-frequency noise filtering in electronic assemblies
• Post-assembly cable protection in manufacturing environments

Procurement Notes

Verify the specific impedance rating required for your application, as sources indicate variations between 110 Ohms and 150 Ohms at 100 MHz. Confirm that the 5.1 mm inner diameter accommodates the target cable bundle. Ensure compliance with RoHS directives if applicable to your region. Check material specifications to confirm compatibility with the intended frequency range.

Selection Notes

Select this component when post-installation access is necessary for cable management. The split core design distinguishes it from solid cores requiring wire threading. Material 43 is suitable for broadband applications. Verify that the physical clearance around the cable supports the external dimensions of 12.8 mm by 5.6 mm.

Part Context

This part belongs to the Round Cable Snap-It series, which are controlled for impedance values. Unlike solid ferrite cores, these assemblies are engineered for convenience in retrofitting or final assembly stages where cable routing is already established.

Replacement Considerations

Solid core equivalents require cable removal for installation. Verify dimensional compatibility with alternative split cores. Ensure substitute parts maintain similar impedance characteristics at operating frequencies.
