2661102002

Overview

The Fair-Rite 2661102002 is a solid round ferrite cable core designed for electromagnetic interference suppression. It utilizes Material 61, providing an impedance of 190 Ohms at 100 MHz. The component features a 12.8 mm inner diameter and measures 25.9 mm in outer diameter with a length of 28.6 mm. It operates effectively within the 250 MHz to 1 GHz frequency range.

Feature Summary

• Constructed from Material 61 ferrite composition optimized for high-frequency noise attenuation
• Solid cylindrical design provides structural integrity without split mechanisms
• Engineered to suppress common-mode noise on cables passing through the central aperture

Applications

• EMI suppression for amateur radio equipment cabling
• Noise reduction for data transmission lines above 200 MHz
• Filtering high-frequency interference on power supply cords

Procurement Notes

Verify that the required impedance specification matches the application's frequency requirements, as Material 61 performance varies across the spectrum. Confirm physical dimensions align with the target cable bundle size, specifically ensuring the 12.8 mm inner diameter accommodates the conductor assembly without excessive force or loose fit.

Selection Notes

Select this part when high-frequency attenuation above 200 MHz is prioritized over lower frequency performance. Material 61 offers distinct characteristics compared to other Fair-Rite compounds like Material 43. Ensure the solid construction meets mechanical constraints where snap-open cores are unsuitable for the installation environment.

Part Context

This component belongs to the Fair-Rite Round Cable Core series, which includes various materials tailored for specific frequency bands. The 2661102002 variant specifically addresses needs requiring robust, non-split ferrite solutions for permanent or semi-permanent cable installations in electronic systems.

Replacement Considerations

Direct substitutes include other Fair-Rite solid round cores with compatible inner diameters and similar impedance profiles. Verify material composition equivalence if replacing with parts from different manufacturers to ensure comparable high-frequency attenuation characteristics.
