475164181

Overview

The Fair-Rite 475164181 is a split-core ferrite clamp designed for electromagnetic interference suppression. It features an openable circular design with a single aperture of 13.05 mm (0.514 inches). The component exhibits an impedance of 53 ohms at 30 MHz and operates within a frequency range from 200 kHz to 30 MHz. External dimensions are 39.5 mm in length, 31 mm in width, and 30 mm in height. It accommodates cable diameters between 2.5 mm and 25.4 mm.

Feature Summary

• Snap-fit hinged construction allows for easy installation over existing cables without disconnection.
• Solid core material formulation provides effective attenuation of high-frequency noise.
• Openable geometry supports round cables or bundled wire configurations.

Applications

• Electromagnetic interference suppression on data lines
• Noise filtering on power supply cables
• Signal integrity enhancement in electronic assemblies

Procurement Notes

Verify the specific impedance curve against your target frequency spectrum, as performance varies across the 200 kHz to 30 MHz range. Confirm that the internal aperture diameter of 13.05 mm adequately fits the maximum bundle diameter of your application. Ensure compliance with RoHS standards if required by your manufacturing environment.

Selection Notes

Select this model when retrofitting existing wiring harnesses where removing connectors is impractical. The split-core design distinguishes it from solid cores, offering convenience for post-assembly integration. Consider the physical envelope of 39.5 x 31 x 30 mm to ensure sufficient clearance within the enclosure.

Part Context

This component belongs to the Fair-Rite snap-it series of openable ferrite clamps. These products are engineered for rapid deployment on cables and wires. The part utilizes specific ferrite materials optimized for broadband noise reduction in the specified frequency band.

Replacement Considerations

Direct substitutes include other Fair-Rite split-core models with compatible aperture sizes and impedance characteristics. Verify dimensional compatibility before swapping to ensure fitment within constrained spaces.

FAQ

What is the maximum cable diameter this clamp can accommodate?

The clamp accommodates round cables or bundled wires with diameters ranging from 2.5 mm to 25.4 mm.

Is this ferrite core solid or split?
