461164281

Overview

The Fair-Rite 461164281 is a ferrite core assembly designed for electromagnetic interference suppression. It features a split-core construction allowing installation around existing cables without disconnection. The material composition utilizes a high-permeability ferrite formulation optimized for noise attenuation in the MHz frequency range. This component serves as a passive filter element to reduce common-mode currents on signal and power lines.

Feature Summary

• Split-core design enables non-intrusive installation on pre-existing wiring harnesses
• High magnetic permeability material provides effective noise absorption across targeted frequency bands
• Robust mechanical housing protects the ferrite material from physical damage and environmental factors

Applications

• Suppression of radio frequency interference on computer peripheral cables
• Noise reduction on industrial control signal wiring
• EMI mitigation on automotive sensor data lines

Procurement Notes

Verify the specific material number associated with the 46 series designation to ensure compatibility with the target frequency spectrum. Confirm that the inner diameter matches the cable bundle diameter precisely to maintain optimal coupling efficiency. Check for any RoHS or REACH compliance documentation required by your regional regulations before finalizing procurement.

Selection Notes

Select this component based on the required impedance profile at the specific noise frequencies encountered in the application. Ensure the current carrying capacity of the cable does not saturate the ferrite core under normal operating conditions. Evaluate the physical space constraints to confirm the split-core geometry fits within the available enclosure or routing path.

Part Context

This part belongs to the Fair-Rite 46 series of ferrite cores, which are widely recognized for their consistent magnetic properties and reliability in EMI suppression applications. The 46 material is specifically engineered for broadband noise reduction, making it suitable for diverse electronic environments where multiple noise sources may be present simultaneously.

Replacement Considerations

Direct replacements must match the original part's outer dimensions, inner diameter, and material permeability characteristics. Verify that substitute components offer equivalent impedance curves at the critical noise frequencies. Consult manufacturer cross-reference lists for approved equivalents that meet the same technical specifications.
