475178281

Overview

Fair-Rite Products Corp. part number 475178281 is a split-core ferrite assembly designed for electromagnetic interference (EMI) suppression. The unit features a round aperture with an internal diameter of 8.99 mm, accommodating cables within this size constraint. It utilizes a polypropylene housing to secure the magnetic material. The core material is optimized for common-mode noise reduction in the frequency range from 200 kHz to 30 MHz. This hinged design allows for installation on existing cable assemblies without requiring disconnection or removal of connectors.

Feature Summary

• Hinged split-core construction enables non-intrusive installation onto pre-existing cable runs
• Polypropylene housing provides structural integrity and environmental protection
• Engineered for effective common-mode conducted EMI suppression across specified frequencies

Applications

• Suppression of common-mode noise on data and power cables
• EMI mitigation in electronic equipment cabling
• Retrofitting noise filtering onto installed wire harnesses

Procurement Notes

Verify the specific cable diameter against the 8.99 mm internal aperture before procurement to ensure proper fit. Confirm that the target application falls within the 200 kHz to 30 MHz operational range for optimal performance. Check for any specific RoHS compliance requirements if applicable to your manufacturing standards. Ensure the polypropylene housing meets any relevant temperature ratings for the intended environment.

Selection Notes

Select this component when retrofitting EMI suppression is required without disconnecting cables. The split-core design is essential for applications where the cable cannot be removed from the system. Consider the 8.99 mm aperture limit when choosing between solid cores and openable variants. Ensure the frequency range of interest aligns with the core material's effectiveness profile.

Part Context

This component belongs to Fair-Rite's cable ferrite product line, specifically categorized as openable or hinged cores. These are distinct from solid snap-on cores due to their ability to clamp around existing wires. The 475178281 model represents a standard solution for general-purpose EMI suppression in commercial and industrial electronics.

Replacement Considerations

Direct substitutes may include other Fair-Rite openable cores with similar aperture sizes, such as the 475178281 equivalent or compatible models from the same series. Verify that alternative parts maintain the 8.99 mm inner diameter and comparable impedance characteristics at 200 kHz to 30 MHz.
