2176746-3

Overview

The TE Connectivity Passive Product 2176746-3 is a power line ferrite bead designed for surface mount applications. It features a 0402 (1005 Metric) package with axial termination. The component provides an impedance of 7 Ohms at 100 MHz and supports a current rating of 1.8A. Its DC resistance is specified as 50mOhm. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression for power lines
• Compact surface mount footprint suitable for high-density layouts
• High current handling capability for power circuit protection

Applications

• Power supply input filtering
• DC-DC converter output stages
• General purpose EMI suppression in portable electronics

Procurement Notes

Verify the exact impedance tolerance and current derating curves against the official datasheet before integration. Confirm that the 0402 package dimensions align with the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when space constraints require a 0402 ferrite bead with moderate current capacity. The 7 Ohm impedance at 100 MHz targets common noise frequencies in digital power systems. Consider the low DC resistance to minimize voltage drop and power loss in the main power path. Evaluate thermal performance under continuous load conditions.

Part Context

This component belongs to the Sigma Inductors passive product family from TE Connectivity. It is categorized as a power line ferrite bead, distinct from signal line chokes or shielded inductors. The product utilizes thin-film or bulk ferrite technology optimized for high-frequency attenuation while maintaining structural integrity in small form factors.
