443164151

Overview

Fair-Rite 443164151 is a split-core ferrite assembly designed for round cables with an internal diameter of 12.7 mm (0.50 inches). Constructed from Fair-Rite Material 43, it provides an impedance of 236 ohms at 100 MHz and 138 ohms at 25 MHz. The unit features a hinged polypropylene case for installation on existing cables without disconnection. It operates within a temperature range of 0°C to 85°C and is RoHS compliant.

Feature Summary

• Split-core design allows installation on terminated cables
• Polypropylene housing for mechanical protection
• Material 43 composition for high-frequency noise suppression

Applications

• Common-mode conducted EMI suppression
• Cable noise filtering in the 25 to 300 MHz range

Procurement Notes

Verify the specific impedance tolerance requirements against the datasheet minimums, as assemblies are controlled for impedance only. Confirm that the cable diameter falls within the specified 12.7 mm aperture limit to ensure proper fit and magnetic coupling efficiency.

Selection Notes

Select this part when retrofitting noise suppression onto existing round cables where solid cores cannot be threaded. Ensure the operating environment stays within the 0°C to 85°C rating. Material 43 is suitable for general-purpose broadband noise reduction in the VHF/UHF spectrum.

Part Context

This component belongs to Fair-Rite's Snap-It series of two-piece ferrite assemblies. Unlike solid cores, these hinged units facilitate maintenance and modification of cable assemblies. They are distinct from bead-style ferrites by their larger aperture and snap-together construction.

Replacement Considerations

No public confirmed substitute part numbers are available.
