2643801502

Overview

Fair-Rite 2643801502 is a solid round ferrite cable core utilizing Material 43 for EMI suppression. It features an inner diameter of 12.70 mm (0.500 inches), an outer diameter of 25.40 mm (1.000 inches), and an external length of 6.35 mm (0.250 inches). The component provides an impedance of 53 Ohms at 100 MHz, operating effectively across broadband frequencies from 25 MHz to 300 MHz.

Feature Summary

• Solid free-hanging design suitable for direct cable mounting
• Material 43 composition optimized for high-frequency noise attenuation
• Broadband performance covering 25 MHz to 300 MHz range

Applications

• Electromagnetic interference suppression on cables
• High-frequency signal line filtering
• Broadband frequency noise reduction

Procurement Notes

Verify the specific Material 43 designation and impedance value of 53 Ohms at 100 MHz against official Fair-Rite datasheets. Confirm dimensional tolerances for the 12.70 mm inner diameter and 25.40 mm outer diameter to ensure compatibility with target cable assemblies prior to procurement.

Selection Notes

Select this component when broadband suppression between 25 MHz and 300 MHz is required. Ensure the cable diameter fits within the 12.70 mm inner diameter constraint. Material 43 is appropriate for applications prioritizing high-frequency attenuation over low-frequency inductance.

Part Context

This part belongs to the Fair-Rite 26 series of round cable cores. It utilizes Material 43, a standard nickel-zinc ferrite formulation designed for effective noise suppression in the VHF and UHF spectrum ranges, distinguishing it from materials optimized for lower frequency power line applications.

Replacement Considerations

Cross-reference with other Fair-Rite 26-series parts using Material 43 if dimensional or impedance specifications require adjustment. Verify that substitute components maintain the 53 Ohm impedance characteristic at 100 MHz for equivalent performance.
