446164951

Overview

Fair-Rite 446164951 is a split core ferrite bead designed for electromagnetic interference suppression. It utilizes Material 43, providing an impedance of 175 ohms at frequencies ranging from 25 MHz to 300 MHz. The component features a circular design with a hinged snap mechanism for easy installation around cables. Key dimensions include a 4.9 mm inner diameter and an overall length of 1.420 inches (36.07 mm). It operates within a temperature range of -55°C to 125°C and complies with RoHS 3 standards.

Feature Summary

• Split core construction allows installation on existing cables without disconnection
• Hinged snap mechanism ensures secure closure and retention
• Material 43 composition provides high impedance in the 25-300 MHz frequency range

Applications

• Electromagnetic interference suppression on data cables
• Noise reduction on power supply lines
• Signal integrity improvement in electronic assemblies

Procurement Notes

Verify that the specific order matches the manufacturer part number 446164951 to ensure correct material composition and impedance characteristics. Confirm that the cable diameter falls within the specified 4.9 mm inner diameter limit before procurement. Check for RoHS 3 compliance requirements if applicable to your assembly standards.

Selection Notes

Select this component when retrofitting ferrite suppression onto existing cabling is required. The split core design eliminates the need to disconnect wires during installation. Ensure the target frequency range aligns with the 25 MHz to 300 MHz specification where Material 43 offers optimal performance. Verify physical clearance for the 1.420 inch length.
