431173551

Overview

Fair-Rite Products Corp. part number 431173551 is a split core ferrite clamp-on component designed for electromagnetic interference suppression. It utilizes Fair-Rite's proprietary 31 material composition, which provides high permeability suitable for low-frequency applications. The device features a circular snap-fit design with an internal cable diameter of 18.5 mm. Key electrical specifications include an impedance of 200 ohms at 25 MHz and 310 ohms at 250 MHz. The physical dimensions are approximately 42 mm in length, 29.5 mm in depth, and 29.5 mm in height.

Feature Summary

• Snap-fit split core design allows installation on existing cables without disconnection
• Utilizes 31 material composition optimized for low-frequency noise attenuation
• Circular geometry accommodates round cable bundles up to specified diameter

Applications

• Electromagnetic interference suppression on power and signal cables
• Low-frequency noise filtering in electronic equipment
• Cable harness noise reduction in industrial systems

Procurement Notes

Verify the manufacturer part number against official Fair-Rite documentation to ensure authenticity. Confirm that the 31 material specification matches the intended frequency range requirements. Check for RoHS compliance status if required by specific project regulations. Ensure the cable diameter does not exceed the 18.5 mm internal opening limit.

Selection Notes

Select this component when low-frequency noise suppression is required using a non-invasive installation method. The 31 material offers higher permeability compared to standard mixtures, making it effective for frequencies below 100 MHz. Ensure the target cable fits within the 18.5 mm aperture. Consider the physical size constraints relative to the available space around the cable bundle.

Part Context

This component belongs to the Fair-Rite SNAP-IT series of split core ferrites. These products are engineered for rapid deployment on pre-existing wiring harnesses. The 31 material variant is distinct from other mixes like 43 or 61, offering specific magnetic properties tailored for lower frequency ranges where high permeability is critical for effective common-mode choke performance.
