431167281

Overview

Fair-Rite part number 431167281 is a split-core ferrite clamp designed for electromagnetic interference (EMI) suppression. It utilizes Fair-Rite Material 43, providing an impedance of 240 ohms at 100 MHz and 125 ohms at 25 MHz. The component features a round shape with a 9.85 mm inner diameter to accommodate cables ranging from 2.5 mm to 25.4 mm in diameter. External dimensions are approximately 39.4 mm in length, 23.7 mm in width, and 11.7 mm in height. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Snap-fit split design allows installation on existing cables without disconnection
• Material 43 composition provides high permeability for broadband noise suppression
• Round geometry accommodates various cable diameters up to 25.4 mm

Applications

• Electromagnetic interference suppression on data and power lines
• Noise reduction on bundled wire assemblies
• Cable filtering in electronic equipment enclosures

Procurement Notes

Verify the exact suffix designation with the manufacturer, as Fair-Rite part numbers often include specific material or configuration codes. Confirm RoHS compliance status directly with the supplier documentation. Ensure the inner diameter specification matches the target cable bundle size before procurement to guarantee proper fit and performance.

Selection Notes

Select this component when broadband EMI suppression is required for cables that cannot be disconnected during assembly. Material 43 is suitable for frequencies between 1 MHz and 300 MHz. Compare impedance values against other materials if specific frequency attenuation characteristics are needed. Verify physical clearance constraints against the external dimensions provided.

Part Context

This component belongs to the Fair-Rite snap-fit ferrite core family, specifically utilizing Material 43 for high-frequency noise absorption. It serves as a passive filter element to mitigate common-mode currents on cables. The split design distinguishes it from solid toroidal cores, offering convenience for retrofits and maintenance scenarios where cable continuity must be preserved.

Replacement Considerations
