2643804502

Overview

The Fair-Rite 2643804502 is a round cable EMI suppression core constructed from Material 43. It provides a guaranteed minimum impedance of 100 ohms at 100 MHz, with an operational frequency range spanning 25 MHz to 300 MHz. The component features a cylindrical geometry with an outer diameter of 1.225 inches (31.12 mm) and an inner diameter of 0.750 inches (19.05 mm). This ferrite bead is designed for effective electromagnetic interference suppression on cables within the specified bandwidth.

Feature Summary

• Utilizes Material 43 composition for optimized high-frequency performance
• Provides guaranteed minimum impedance specifications for reliable noise suppression
• Cylindrical design facilitates easy installation around existing cabling

Applications

• Electromagnetic interference suppression
• High-frequency signal line filtering
• Cable noise reduction in electronic assemblies

Procurement Notes

Verify the specific material grade and impedance tolerance against the official Fair-Rite datasheet before procurement. Confirm that the physical dimensions match the required cable outer diameter constraints. Ensure compliance with RoHS standards if applicable to the end application. Cross-reference the part number with authorized distributors to confirm current availability and authenticity.

Selection Notes

Select this component when a round ferrite core with Material 43 properties is required for frequencies between 25 MHz and 300 MHz. The 100-ohm impedance at 100 MHz makes it suitable for general-purpose EMI suppression. Ensure the cable diameter fits within the 0.750-inch inner diameter clearance. Consider the cylindrical form factor for applications requiring non-split core installation.

Part Context

This part belongs to the Fair-Rite Round Cable EMI Suppression Cores series. The numbering convention indicates Product Class 26 and Material Grade 43. These cores are engineered for controlled impedance characteristics to ensure consistent noise attenuation across various cable types and sizes within the designated frequency spectrum.

Replacement Considerations

Direct substitutes must share Material 43 composition and similar dimensional constraints. Verify impedance curves at 100 MHz to ensure equivalent noise suppression performance. Alternative parts should maintain the cylindrical shape and compatible inner diameter for direct interchangeability without mechanical modification.
