446164281

Overview

Fair-Rite 446164281 is a round cable snap-on ferrite core manufactured from 46 material. It features an inner diameter of 6.60 mm (0.260 inches) and external dimensions of 20.02 mm width by 38.5 mm height. The component provides an impedance of 235 Ohms at 100 MHz. Designed for hinged installation, it allows for easy clamping around cables without disconnection.

Feature Summary

• Snap-on design enables rapid installation on existing cables
• Utilizes 46 material composition for high-frequency noise suppression
• Hinged construction facilitates access to enclosed wiring

Applications

• Electromagnetic interference suppression in electronic assemblies
• Common-mode noise filtering on data and power lines
• Retroactive noise mitigation on installed cable harnesses

Procurement Notes

Verify the exact part number against official Fair-Rite documentation, as similar identifiers like 461164281 or 0446164281 exist with distinct specifications. Confirm material grade and impedance ratings match the specific application requirements before procurement. Ensure compatibility with the target cable diameter.

Selection Notes

Select this component when retrofitting noise suppression onto existing cables is required. The snap-on form factor is critical for applications where cable disconnection is impractical. Verify that the 6.60 mm inner diameter accommodates the target cable bundle size while maintaining sufficient magnetic coupling for effective attenuation.

Part Context

This component belongs to the Fair-Rite Round Cable Snap-It series. These cores are engineered for convenient attachment to wires and cables. The 46 material variant is optimized for higher frequency ranges compared to standard 43 material cores, providing enhanced performance in suppressing high-frequency electromagnetic interference.

Replacement Considerations

Direct substitutes may include other Fair-Rite snap-on cores with matching 46 material properties and compatible inner diameters. Cross-reference dimensional constraints and impedance curves to ensure equivalent noise suppression capabilities in the target frequency range.
