444167281

Overview

Fair-Rite part number 444167281 is a round cable snap-on ferrite core designed for electromagnetic interference suppression. It utilizes Fair-Rite Materials 43 and 44, providing an impedance of 210 Ω at 100 MHz and 125 Ω at 25 MHz. The component features a single opening with an inner diameter of 10.15 mm (0.400 inches). Physical dimensions are 23.7 mm in width, 39.4 mm in height, and 11.7 mm in depth. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Snap-on design allows easy installation around existing cables without disconnection
• Dual-material composition supports broad frequency attenuation performance
• Free-hanging configuration enables flexible mounting orientations

Applications

• Electromagnetic interference suppression on round cables
• Noise filtering on bundled wire assemblies
• Cable protection for diameters between 2.5 mm and 25.4 mm

Procurement Notes

Verify the exact material composition required for your specific frequency application, as this part combines Material 43 and Material 44. Confirm that the cable diameter falls within the specified 10.15 mm inner diameter tolerance. Ensure environmental conditions remain within the -55°C to +125°C operating range. Check for RoHS compliance requirements if applicable to your manufacturing standards.

Selection Notes

Select this component when high-frequency noise suppression is needed on cables that cannot be easily disconnected. The snap-on style offers convenience over solid cores. Consider the combined Material 43/44 properties for balanced low and high-frequency attenuation. Verify physical space constraints against the 23.7 mm x 39.4 mm footprint.

Part Context

This part belongs to Fair-Rite's Round Cable Snap-Its series. These components are engineered specifically for rapid deployment on round conductors. They differ from split-core designs by offering a more secure mechanical fit for standard circular cables. The series provides various impedance values to match different EMI profiles.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Equivalent parts must match the 10.15 mm inner diameter and similar impedance characteristics at 100 MHz.
