2743037447

Overview

Fair-Rite part number 2743037447 is a differential-mode ferrite bead utilizing 43 material composition. It features an SMD J-lead package in the 1812 [4532 Metric] footprint. The component provides an impedance of 95 ohms at 100 MHz and 100 ohms at 250 MHz, with a maximum DC resistance of 1.2 milliohms.

Feature Summary

• Differential-mode noise suppression for signal integrity
• Low DC resistance to minimize power loss
• J-lead surface mount design for secure attachment

Applications

• High-speed data line filtering
• USB interface protection
• HDMI signal conditioning

Procurement Notes

Verify the specific impedance tolerance and material lot consistency against the manufacturer's current datasheet before integration. Confirm that the J-lead termination style matches the target PCB land pattern dimensions to ensure proper solder joint reliability during assembly.

Selection Notes

Select this component when differential noise attenuation is required without introducing significant series resistance. The 43 material offers high permeability suitable for broadband suppression. Ensure the operating frequency range aligns with the peak impedance characteristics provided in the official electrical specifications.

Part Context

This component belongs to Fair-Rite’s SM Beads series designed for surface mount applications. It utilizes proprietary 43 material formulation optimized for suppressing common-mode and differential interference in compact electronic assemblies where space constraints limit the use of larger through-hole solutions.

Replacement Considerations

Cross-reference with other 1812 footprint ferrite beads using 43 material. Verify that substitute parts maintain equivalent J-lead terminal geometry and meet the same 1.2 milliohm DC resistance specification to preserve circuit performance.
