2643001601

Overview

The Fair-Rite Products Corp. part number 2643001601 is a solid, free-hanging ferrite core designed for EMI suppression applications. It utilizes Material 43 and provides an impedance of 30 Ohms at 100 MHz. The component features a round cable design with an inner diameter of 1.78 mm (0.070 inches), an outer diameter of 3.56 mm (0.140 inches), and a length of 3.10 mm (0.122 inches). It operates within a temperature range of -55°C to +125°C and has an inductance of 430 pH.

Feature Summary

• Solid construction eliminates the need for assembly hardware
• Material 43 composition optimized for high-frequency noise suppression
• Free-hanging installation allows flexible cable routing

Applications

• Suppression of electromagnetic interference on small gauge cables
• Common-mode noise reduction in electronic assemblies
• Signal integrity enhancement in high-speed data lines

Procurement Notes

Verify the specific impedance value and material designation against the manufacturer's current datasheet before integration. Confirm that the physical dimensions match the available cable diameter to ensure proper fit. Check for any recent product change notifications regarding material sourcing or manufacturing origin updates from Fair-Rite.

Selection Notes

Select this component when a compact, low-profile ferrite solution is required for cables with diameters near 1.78 mm. Material 43 is suitable for frequencies typically above 10 MHz. Ensure the operating temperature environment remains within the specified -55°C to +125°C range for reliable performance.

Part Context

This component belongs to the Fair-Rite 2643 series of solid ferrite cores. These parts are distinct from split-core designs as they require the cable to be threaded through during initial assembly. The series offers various materials and impedances to target specific noise frequency profiles.

Replacement Considerations

Part 2643001501 is a similar solid core but uses Material 43 with a 35 Ohm impedance and different dimensions (ID 1.60mm). Verify dimensional compatibility and impedance requirements before substitution.
