5943001801

Overview

Fair-Rite part number 5943001801 is a solid free-hanging ferrite core designed for cable electromagnetic interference suppression. The component utilizes Fair-Rite Material 43, which provides high permeability suitable for noise reduction in the frequency range of 20 MHz to 300 MHz. It features a cylindrical geometry with an inner diameter of 13.70 mm (0.539 inches), an outer diameter of 22.10 mm (0.870 inches), and a length of 6.35 mm (0.250 inches). This configuration allows it to be slipped over cables without requiring soldering or complex mounting hardware.

Feature Summary

• Constructed from Fair-Rite Material 43 for effective high-frequency noise attenuation
• Solid free-hanging design enables easy installation directly onto cables
• Cylindrical shape accommodates various cable diameters within its aperture

Applications

• Electromagnetic interference suppression on data and power cables
• High-frequency noise filtering in electronic assemblies
• Common mode choke applications for signal integrity enhancement

Procurement Notes

Verify that the selected distributor source matches the official Fair-Rite manufacturing specifications. Confirm the material designation is explicitly listed as Material 43 to ensure correct impedance characteristics. Check package quantity details against your inventory requirements. Ensure the physical dimensions align with your cable assembly constraints before finalizing the order.

Selection Notes

Select this component when a non-solderable, snap-on ferrite solution is required for frequencies above 20 MHz. Material 43 offers higher permeability than standard mixtures, making it ideal for suppressing broadband noise. Compare the 13.70 mm inner diameter against available cable sizes to ensure a secure fit. Consider the free-hanging form factor if board space is limited but cable routing requires EMI protection.

Part Context

This part belongs to the Fair-Rite solid free-hanging ferrite core series. These components are distinct from split cores or toroidal rings intended for winding. They are specifically engineered for post-assembly cable treatment rather than integrated circuit packaging. The product line supports various material compositions tailored to specific frequency bands.

Replacement Considerations
