2643012702

Overview

Fair-Rite Products Corp. part number 2643012702 is a solid cylindrical ferrite cable core designed for electromagnetic interference suppression. It utilizes Fair-Rite Material 43, providing an impedance of 38 ohms at a test frequency of 100 MHz. The component features a free-hanging installation type with specific physical dimensions: an inner diameter of 0.250 inches (6.35 mm), an outer diameter of 0.380 inches (9.65 mm), and a length of 0.290 inches (7.37 mm).

Feature Summary

• Solid cylindrical construction made from Material 43 for broadband noise attenuation.
• Free-hanging design allows for easy sliding onto cables without specialized mounting hardware.
• Provides 38 ohms impedance at 100 MHz to suppress common mode noise.

Applications

• Suppression of electromagnetic interference on power and signal cables.
• Noise filtering in electronic equipment wiring harnesses.
• Common mode choke applications for data transmission lines.

Procurement Notes

Verify the manufacturer part number 2643012702 against official Fair-Rite documentation to ensure material composition matches Material 43 specifications. Confirm that the required impedance characteristics align with the target frequency range of application. Check RoHS compliance status if restricted substances are a constraint for the end product.

Selection Notes

Select this component when a low-impedance solution is required for smaller gauge cables fitting within a 6.35 mm inner diameter. Material 43 is suitable for frequencies ranging from 25 MHz to several hundred MHz. Ensure the physical length of 7.37 mm provides sufficient attenuation for the specific noise profile compared to higher impedance alternatives.

Part Context

This component belongs to the Fair-Rite 26 series of round cable cores. It is distinct from split-core designs or multi-aperture rings, offering a continuous magnetic path for consistent performance. The solid construction differentiates it from snap-fit variants, requiring manual placement onto the wire during assembly.
