2744555566

Overview

The Fair-Rite 2744555566 is a surface-mount ferrite chip bead designed for differential mode noise suppression. It features a two-terminal SMD/SMT termination configuration and operates within a temperature range of -55°C to +125°C. The component provides an impedance of 414 ohms at 100 MHz, with a maximum DC resistance of 1.1 milliohms. It is RoHS compliant and manufactured under the Fair-Rite brand.

Feature Summary

• Provides differential mode noise attenuation for signal integrity protection
• Utilizes surface-mount technology for automated PCB assembly compatibility
• Constructed from specialized ferrite material optimized for high-frequency absorption

Applications

• High-speed data line filtering in electronic circuits
• Differential pair noise suppression on printed circuit boards
• Electromagnetic interference mitigation in compact consumer electronics

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Fair-Rite datasheet prior to integration. Confirm that the surface-mount footprint dimensions align precisely with the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the RoHS compliance status with current regulatory standards for the destination market.

Selection Notes

Select this component when differential mode noise reduction is required rather than common-mode suppression. Evaluate the trade-off between the low DC resistance and the target impedance level for the specific frequency band. Consider the physical size constraints of the board layout relative to the standard SMD package dimensions. Verify thermal performance capabilities under expected load conditions.

Part Context

This part belongs to the Fair-Rite series of ferrite chip beads, which are passive components used for EMI suppression. Unlike common-mode chokes, these devices are configured to attenuate noise currents flowing in opposite directions on paired lines. They serve as critical elements in maintaining signal quality in high-frequency digital and analog interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineers must consult the manufacturer's official cross-reference tools or equivalent technical specifications to identify compatible alternatives.
