2643101902

Overview

Fair-Rite 2643101902 is a round cable EMI suppression core utilizing 43-grade ferrite material. It features an inner diameter of 13.79 mm (0.543 inches), an outer diameter of 28.50 mm (1.122 inches), and a length of 28.58 mm (1.125 inches). The component provides a minimum impedance of 230 ohms at 100 MHz and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Constructed from 43-grade ferrite material for high-frequency inductive applications
• Designed as a solid, free-hanging cylindrical core for cable mounting
• Provides guaranteed minimum impedance specifications for effective common-mode choke performance

Applications

• High frequency common-mode chokes
• EMI suppression on cables
• Inductive applications requiring specific impedance characteristics

Procurement Notes

Verify the exact physical dimensions and impedance values against the official Fair-Rite datasheet before integration. Confirm that the 43-grade material composition aligns with your specific frequency requirements. Ensure the free-hanging design fits your mechanical assembly constraints without additional mounting hardware.

Selection Notes

Select this part when a cylindrical ferrite core with a 13.79 mm inner diameter is required. The 43 material grade is suitable for frequencies where moderate permeability and low loss are needed. Compare the 230 ohm impedance at 100 MHz against other materials if higher or lower attenuation is necessary for your specific noise spectrum.

Part Context

This component belongs to the Fair-Rite 2643 series of round cable EMI suppression cores. These cores are widely used for suppressing electromagnetic interference on wires and cables. The 2643101902 variant specifically utilizes Material 43, which is optimized for general-purpose noise suppression in the VHF and UHF ranges.

Replacement Considerations

Check Fair-Rite's Material 43 product line for alternative sizes. Verify that any substitute maintains the same inner diameter tolerance and impedance profile at 100 MHz to ensure equivalent circuit performance.
