444164181

Overview

Fair-Rite part number 444164181 is a split-core ferrite clamp designed for round cables. It utilizes a composite of Material 43 and Material 44 to provide electromagnetic interference suppression. The component features an inner diameter of 13.05 mm (0.514 inches) and external dimensions of 31 mm x 39.4 mm x 15.25 mm. Impedance specifications include 230 ohms at 100 MHz and 138 ohms at 25 MHz, with a maximum impedance of 280 ohms at 250 MHz.

Feature Summary

• Split-core design allows installation around existing cables without disconnection
• Composite material construction combines Material 43 and Material 44 properties
• Controlled impedance characteristics for effective noise suppression

Applications

• Electromagnetic interference suppression on round cables
• Noise filtering in electronic assemblies
• Cable protection in industrial environments

Procurement Notes

Verify the exact material composition and impedance values against the manufacturer's current datasheet before integration. Confirm that the split-core mechanism provides sufficient clamping force for the target cable diameter. Ensure compliance with relevant environmental regulations such as RoHS standards applicable to your region.

Selection Notes

Select this component when retrofitting ferrite suppression onto installed cabling is required. The dual-material formulation offers broad frequency effectiveness compared to single-material cores. Verify that the 13.05 mm inner diameter accommodates the specific cable bundle size with appropriate clearance for mechanical stability.

Part Context

This part belongs to Fair-Rite's Snap-It series of round cable ferrite assemblies. These components are engineered for controlled impedance performance rather than simple inductance. The product line focuses on providing flexible EMI solutions for various cable diameters using standardized core geometries.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacements require matching the inner diameter, material composition, and impedance profile to ensure equivalent electromagnetic performance.
