443178181

Overview

Fair-Rite Products Corp. part number 443178181 is a split core ferrite bead designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 125 ohms at 100 MHz. The component features a circular shape with a hinged snap-fit design for easy installation on cables without disconnection. Internal dimensions specify a diameter of 0.169 inches (4.29 mm), while external dimensions are 0.465 inches wide by 0.221 inches high and 0.913 inches long. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Hinged snap-fit design allows for rapid installation on existing cables without breaking the circuit loop.
• Material 43 composition provides effective high-frequency noise attenuation characteristics.
• Circular geometry accommodates round cable profiles securely.

Applications

• Electromagnetic interference suppression on data and power cables
• Signal integrity enhancement in electronic assemblies
• Retrofit noise filtering on manufactured wiring harnesses

Procurement Notes

Verify the specific material grade and impedance specifications against the official Fair-Rite datasheet prior to procurement. Confirm that the cable diameter falls within the 4.29 mm internal bore limit. Ensure the application environment remains within the specified -55°C to +125°C operating temperature range to maintain material performance and structural integrity of the hinge mechanism.

Selection Notes

Select this component when non-invasive installation on pre-assembled cables is required. The Material 43 formulation is suitable for general-purpose noise suppression in the frequency range above 100 MHz. Compare internal dimensions against target cable diameters to ensure a secure fit. Consider the Snap-It series compatibility if multiple core types are used in the same assembly for standardized handling procedures.

Part Context

This component belongs to the Fair-Rite Snap-It series of split core ferrites. These cores are engineered for field installation where traditional solid cores cannot be applied due to fixed cable ends. The product line emphasizes ease of use and reliable retention on various cable sizes through its proprietary hinge and latch mechanism.

Replacement Considerations

Part number 0461178181 is documented as a parameter equivalent substitute. Verify dimensional compatibility and impedance curves before substitution.

FAQ

What is the maximum cable diameter supported by this ferrite core?

The internal diameter is 0.169 inches (4.29 mm), which defines the maximum cable diameter for proper installation.

Is this ferrite core reusable after installation?

Yes, the hinged snap-fit design allows the core to be opened and closed repeatedly for inspection or repositioning.
