431173951

Overview

Fair-Rite part number 431173951 is a Round Cable Snap-It ferrite core assembly manufactured by Fair-Rite Products Corp. It utilizes Material 31, which provides high permeability for effective electromagnetic interference suppression in the lower frequency range. The component is designed as a split-core assembly that snaps shut around cables without requiring disconnection. It accommodates round cables or bundled wires with diameters ranging from 2.5 mm (0.100 inches) to 25.4 mm (1.000 inches). The product is controlled for impedance values at specific frequencies.

Feature Summary

• Snap-It design allows for easy installation around existing cables without disconnecting them
• Utilizes Material 31 composition for optimized low-frequency noise attenuation
• Accommodates a wide range of cable diameters from 2.5 mm to 25.4 mm

Applications

• Suppression of electromagnetic interference on round cables and wire bundles
• Low-frequency noise filtering in electronic equipment cabling
• Retrofit EMI mitigation on installed wiring harnesses

Procurement Notes

Verify the exact impedance specifications required for your application against the official datasheet, as performance varies with frequency. Confirm compatibility with the target cable diameter, ensuring it falls within the 2.5 mm to 25.4 mm range. Check for RoHS compliance status if required by your manufacturing standards. Ensure the supplier provides the genuine Fair-Rite product to guarantee material properties.

Selection Notes

Select this component when low-frequency noise suppression is needed and cable disconnection is impractical. Material 31 is suitable for applications where higher permeability is preferred over high saturation current. Ensure the cable diameter fits within the specified operational range. Consider the physical size constraints of the installation area before choosing this snap-on assembly.

Part Context

This part belongs to the Fair-Rite Round Cable Snap-It series, offering a convenient alternative to solid or split cores that require tools for installation. The Snap-It assemblies are specifically engineered for rapid deployment on existing cables. They provide consistent impedance characteristics across the designated cable diameter range, making them reliable for standard EMI suppression tasks.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When replacing, ensure the new component matches the Material 31 specification and the impedance profile at relevant frequencies. Verify that the replacement also supports the same cable diameter range and maintains the snap-fit mechanical design.
