2643001501

Overview

Fair-Rite 2643001501 is a solid, free-hanging ferrite core designed for EMI suppression. It utilizes Material 43, providing an impedance of 35 Ohms at 100 MHz. The component features a circular design with an inner diameter of 1.60 mm (0.063 inches), an outer diameter of 3.51 mm (0.138 inches), and a length of 3.25 mm (0.128 inches). It operates within a temperature range of -55°C to +90°C and is RoHS compliant.

Feature Summary

• Solid construction ensures mechanical stability without requiring assembly hardware
• Material 43 composition provides effective broadband noise attenuation from 25 to 300 MHz
• Free-hanging installation allows direct sliding onto cables or wires

Applications

• Suppression of electromagnetic interference on high-speed data lines
• Noise reduction on power supply cables in electronic equipment
• EMI mitigation in telecommunications signal wiring

Procurement Notes

Verify the specific Fair-Rite part number 2643001501 against official manufacturer documentation to confirm Material 43 composition and dimensional tolerances. Ensure compatibility with cable diameters up to 1.60 mm inner diameter. Confirm RoHS compliance status if required by project specifications. Cross-reference datasheet values for impedance characteristics at target frequencies.

Selection Notes

Select this component when broadband suppression between 25 and 300 MHz is required using Material 43. The solid, free-hanging format suits applications where space is limited and permanent attachment is unnecessary. Verify that the target cable diameter fits within the 1.60 mm inner diameter constraint. Consider thermal limits of -55°C to +90°C for environmental suitability.

Part Context

This component belongs to the Fair-Rite Shield Bead series, specifically engineered for EMI suppression. It is categorized under cable ferrites and coils/transformers (FSC 5950). The product is identified by NSN 5950-01-336-3729 as a Shielding Bead, Electronic. It is distinct from split-core designs due to its solid, one-piece construction.
