2176746-5

Overview

The TE Connectivity 2176746-5 is a power line ferrite bead designed for surface mount applications. It features an impedance of 11 Ohms at 100 MHz and operates within a temperature range of -40°C to +125°C. The component supports a maximum DC current of 1.8A with a maximum DC resistance of 50mOhm. Housed in a compact 0402 (1005 metric) package, it measures 1mm in length and 0.5mm in width. This single-element device is engineered for effective noise suppression in high-current power circuits.

Feature Summary

• Provides targeted electromagnetic interference suppression on power lines
• Supports high continuous current handling capabilities
• Utilizes a compact surface mount footprint for dense layouts

Applications

• Power supply input filtering
• DC-DC converter output stages
• High-speed digital power rail noise reduction

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official datasheet before ordering. Confirm that the 0402 package dimensions align with your PCB land pattern specifications. Ensure the operating temperature range meets your environmental conditions. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when space constraints require a small form factor without sacrificing current capacity. The 1.8A rating makes it suitable for moderate power applications where standard signal-grade beads would fail. Consider the 11 Ohm impedance value relative to the target noise frequency spectrum to ensure effective attenuation characteristics are met.

Part Context

This ferrite bead belongs to TE Connectivity's Sigma Inductors passive product line. It is part of a broader family of chip beads designed for general-purpose EMI suppression. The 2176746-5 variant specifically targets power line applications requiring robust current handling alongside noise filtration in compact electronic assemblies.

Replacement Considerations

Check for direct substitutes such as the 2176746-6 or 1-2176746-5 if impedance variations are acceptable. Verify package compatibility and current ratings before swapping. Consult official substitution guides to ensure electrical performance matches the original design intent.
