2661480002

Overview

The Fair-Rite 2661480002 is a solid round cable ferrite core designed for electromagnetic interference (EMI) suppression. It utilizes Material Grade 43, which provides high permeability for effective noise attenuation in the frequency range of interest. The component features a circular cross-section with an inner diameter of 5.08 mm and an outer diameter of 12.32 mm. Its impedance characteristic is specified as 210 Ohms at 100 MHz. The physical length of the core is 25.40 mm. This part belongs to the 61 Round Cable Core product class within the Fair-Rite catalog.

Feature Summary

• Solid construction suitable for free-hanging installation on cables
• Material Grade 43 formulation optimized for common-mode noise suppression
• Round geometry allows for easy sliding onto existing wire assemblies

Applications

• Suppression of electromagnetic interference on data cables
• Noise reduction on power supply lines
• Common-mode choke application for signal integrity enhancement

Procurement Notes

Verify that the required inner diameter of 5.08 mm accommodates the target cable bundle without excessive force or looseness. Confirm that the Material Grade 43 characteristics align with the specific frequency spectrum of the noise being suppressed. Ensure the physical dimensions fit within the available spatial constraints of the assembly. Cross-reference the part number to distinguish between similar products with different material grades or dimensions.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent attachment to a cable. The choice depends on matching the cable diameter to the 5.08 mm inner bore. Consider Material Grade 43 for applications requiring high initial permeability. Evaluate the 210 Ohm impedance at 100 MHz against the noise frequencies present in the system to ensure adequate attenuation performance.

Part Context

This component is part of Fair-Rite's extensive line of magnetic suppression materials. It falls under the category of round cable cores, distinct from split cores or planar geometries. The numbering system indicates its classification as a standard round core utilizing specific magnetic properties defined by the material grade digits.

Replacement Considerations

Direct substitutes include other Fair-Rite parts with identical dimensions but different material grades, such as 2661310002 or 2661610002, if the impedance profile needs adjustment. Verify compatibility before swapping materials as magnetic properties vary significantly across grades.
