446167251

Overview

Fair-Rite Products Corp. part number 446167251 is a split core ferrite assembly designed for electromagnetic interference suppression on round cables. It utilizes Fair-Rite Material 46, which provides high permeability suitable for low-frequency noise attenuation. The component features a hinged snap-on design allowing installation without disconnecting the cable. Key electrical specifications include an impedance of 300 ohms at 25 MHz and 202 ohms at 300 MHz. The internal diameter accommodates cables up to 9.85 mm.

Feature Summary

• Split core construction with a hinged mechanism for easy installation around existing cables
• Utilizes Material 46 composition optimized for high permeability in low-frequency applications
• Snap-on design allows secure attachment to round cables or wire bundles

Applications

• Electromagnetic interference suppression on round cables
• Noise filtering on bundled wires
• Low-frequency signal integrity enhancement

Procurement Notes

Verify that the specific order corresponds to part number 446167251, distinct from similar identifiers like 0446167251 or 446167251 found in distributor databases. Confirm the material designation is 46 and the impedance values match the 25 MHz and 300 MHz requirements. Ensure the cable diameter does not exceed the 9.85 mm internal limit.

Selection Notes

Select this component when low-frequency noise suppression is required using Material 46. The split core design is essential for retrofitting or installing on terminated cables where removal is not feasible. Verify that the target cable diameter fits within the 9.85 mm internal clearance. Consider the impedance profile at 25 MHz and 300 MHz against the specific noise frequencies present in the application.

Part Context

This part belongs to the Fair-Rite Round Cable Snap-It series, which are controlled for impedance values. These assemblies are engineered to accommodate round cables or bundled wires with diameters ranging from 2.5 mm to 25.4 mm. The product line focuses on providing flexible EMI solutions for various cable sizes without requiring disconnection.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must verify compatibility based on material type (Material 46), impedance characteristics, and physical dimensions when evaluating alternatives.
