431177081

Overview

Fair-Rite part number 0431177081 is a split-core ferrite clamp designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 31, providing an impedance of 98 ohms at 25 MHz and 182 ohms at 100 MHz. The component features a circular openable design with a single aperture measuring 25.65 mm in diameter. External dimensions are 56.4 mm in width, 42.95 mm in height, and 27.45 mm in depth. It operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Split-core construction allows installation on existing cables without disconnection
• Material 31 composition provides high impedance characteristics for broadband noise attenuation
• Circular geometry accommodates round cable bundles efficiently

Applications

• Electromagnetic interference suppression on power and signal cables
• Noise reduction in electronic equipment cabling assemblies
• Broadband filtering for high-frequency transient mitigation

Procurement Notes

Verify the exact material grade and impedance specifications against the manufacturer's current datasheet before integration. Confirm that the internal diameter meets the maximum cable outer diameter requirements of the target application. Ensure compliance with relevant environmental regulations such as RoHS for the specific production batch.

Selection Notes

Select this component when retrofitting EMI suppression onto pre-assembled cable harnesses where solid cores cannot be installed. Material 31 is suitable for applications requiring effective noise absorption across a broad frequency spectrum. Ensure the cable bundle diameter fits within the 25.65 mm aperture limit to maintain proper magnetic coupling.

Part Context

This part belongs to the Fair-Rite openable ferrite core family, engineered for convenient field installation. Unlike solid cores, these clamps facilitate maintenance and modification of cable systems. They are widely used in industrial and commercial electronics to mitigate conducted emissions without disrupting existing wiring infrastructure.
