2661801902

Overview

Fair-Rite 2661801902 is a solid round ferrite cable core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 45, providing an impedance of 45 Ohms at 100 MHz. The component features a free-hanging design with an inner diameter of 7.93 mm (0.312 inches), an outer diameter of 12.70 mm (0.500 inches), and a length of 12.70 mm (0.500 inches). It is RoHS compliant and supplied in bulk packaging.

Feature Summary

• Solid round construction for secure cable mounting
• Material 45 composition optimized for high-frequency noise attenuation
• Free-hanging installation style suitable for various cable diameters

Applications

• Electromagnetic interference suppression on cables
• Common mode noise reduction in electronic assemblies
• Signal integrity enhancement in high-frequency circuits

Procurement Notes

Verify the specific Material 45 designation and impedance characteristics against your frequency requirements. Confirm that the 7.93 mm inner diameter accommodates the target cable bundle. Ensure compliance with RoHS standards if required by your manufacturing process. Check for any specific handling instructions regarding solid ferrite cores.

Selection Notes

Select this part when Material 45 properties are required for the target frequency range. The 45 Ohm impedance at 100 MHz indicates suitability for specific EMI bands. Compare the 7.93 mm bore size against available cable options to ensure a proper fit. Consider the solid design for applications requiring robust mechanical attachment without split halves.

Part Context

This component belongs to the Fair-Rite ferrite cable core family, specifically utilizing Material 45. Material 45 is known for its performance in the VHF and UHF ranges, offering high permeability and resistivity. The 26618 series denotes solid round cores, distinguishing them from split or snap-on variants.

Replacement Considerations

Direct substitutes must match the Material 45 specification and similar impedance profile. Verify dimensional compatibility, particularly the 7.93 mm inner diameter. Alternative materials may offer different impedance curves; consult Fair-Rite technical data for equivalent performance across the operating spectrum.
