2646102002

Overview

Fair-Rite Products Corp. part number 2646102002 is a solid, free-hanging round ferrite core designed for electromagnetic interference (EMI) suppression. The component utilizes Material Grade 46, providing an impedance of 212 Ohms at a test frequency of 100 MHz. It features a circular geometry with an inner diameter of 0.505 inches (12.83 mm), an outer diameter of 1.020 inches (25.91 mm), and a length of 1.125 inches (28.58 mm). This cable ferrite is manufactured in bulk packaging and is currently active.

Feature Summary

• Solid construction provides structural integrity for free-hanging installation on cables.
• Material Grade 46 formulation offers specific high-frequency noise attenuation characteristics.

Applications

• Electromagnetic interference suppression on power and signal cables
• Common mode choke applications for data lines
• Retrofitted noise filtering for existing wire assemblies

Procurement Notes

Verify the Material Grade 46 specification against your target frequency range to ensure adequate impedance performance. Confirm that the 12.83 mm inner diameter accommodates the specific cable gauge being treated. Check RoHS compliance status if required by your assembly standards. Ensure the solid design meets mechanical clearance requirements within the final enclosure.

Selection Notes

Select this component when a robust, non-split core is required for permanent cable treatment. Material 46 is suitable for frequencies above 10 MHz. Compare the 212 Ohm impedance value against system noise spectra. Consider the physical dimensions to ensure the core fits around the cable bundle without excessive strain.

Part Context

The 2646 series denotes Fair-Rite's round cable cores. The suffix '46' indicates the magnetic material composition, optimized for higher frequency EMI suppression compared to lower grade materials like 43. This specific model represents a standard size within the product line for medium-gauge cable applications.

Replacement Considerations

Direct substitutes include other Material 46 cores with similar impedance profiles, such as Fair-Rite 2646102002 variants or equivalent parts from other manufacturers offering Grade 46 material. Verify dimensional compatibility before substitution.
