2646480002

Overview

The Fair-Rite Products Corp. model 2646480002 is a solid, free-hanging ferrite core designed for electromagnetic interference suppression. Constructed from Material 43, this cylindrical component provides an impedance of 212 Ohms at 100 MHz. It features an inner diameter of 5.08 mm (0.200 inches), an outer diameter of 12.32 mm (0.485 inches), and a length of 25.40 mm (1.000 inch). The part is RoHS compliant and currently in active production.

Feature Summary

• Solid cylindrical construction for secure cable retention
• Material 43 composition optimized for high-frequency noise attenuation
• Free-hanging design allows easy installation on existing wiring

Applications

• Electromagnetic interference suppression components
• Cable filtering applications
• Printer internal wiring protection

Procurement Notes

Verify the specific Material 43 designation and impedance tolerance against the official Fair-Rite datasheet before integration. Confirm that the 5.08 mm inner diameter accommodates the target cable bundle without excessive friction or clearance issues. Ensure compliance with relevant environmental regulations such as RoHS requirements for the intended market.

Selection Notes

Select this component when a solid, non-split ferrite core is required for permanent cable assembly rather than field service. Material 43 is suitable for frequencies above 25 MHz, making it appropriate for digital signal lines and switching power supplies. Consider the fixed inner diameter constraint during initial harness design to ensure proper fitment.

Part Context

This part belongs to the Fair-Rite round cable EMI suppression core series. These cores are widely used in electronics manufacturing to mitigate common-mode noise on cables. The 2646480002 variant specifically utilizes Material 43, which offers higher permeability compared to standard mixtures, providing effective suppression in compact spaces.

Replacement Considerations

Direct substitutes must match the 5.08 mm inner diameter and Material 43 composition. Alternative Fair-Rite part numbers with different lengths or impedances may serve if physical constraints allow. Verify that any replacement maintains the 212 Ohm @ 100 MHz performance characteristic.
