2176744-9

Overview

The TE Connectivity 2176744-9 is a single-channel power line ferrite bead designed for surface-mount applications. It features an 0805 (2012 metric) package and provides an impedance of 31 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current of 3 A with a maximum DC resistance of 50 mOhms. It operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides high-current suppression capabilities for power lines
• Designed for compact surface-mount integration
• Offers stable impedance characteristics across the operating temperature range

Applications

• Power supply input filtering
• DC-DC converter output noise reduction
• High-speed digital signal line protection

Procurement Notes

Verify the specific datasheet version for the 2176744-9 to confirm exact mechanical dimensions and soldering profiles. Ensure compatibility with automated pick-and-place equipment due to the 0805 package size. Check for any automotive qualification requirements if used in vehicle electronics, as specifications may vary by application grade.

Selection Notes

Select this component when a 31 Ohm impedance at 100 MHz is required for power line filtering. The 3 A current rating makes it suitable for higher power applications compared to standard signal beads. Consider the 0805 footprint constraints and ensure the PCB layout accommodates the thermal dissipation needs associated with the 50 mOhm DC resistance.

Part Context

This part belongs to the TE Connectivity Sigma Inductors passive product family. It is categorized under ferrite beads and chips, specifically engineered for electromagnetic interference suppression in modern electronic circuits. The product represents a solution for managing noise in space-constrained designs requiring robust current handling.

Replacement Considerations

Direct substitutes include other 0805 ferrite beads with similar 31 Ohm impedance and 3 A current ratings from manufacturers like Murata or TDK. Verify that replacement parts match the 50 mOhm DC resistance and 100 MHz test frequency specifications to maintain circuit performance.
