2176746-4

Overview

The TE Connectivity 2176746-4 is a single-element ferrite chip bead designed for surface mount technology in a compact 0402 (1005 metric) package. It provides an impedance of 9 ohms at 100 MHz with a maximum DC resistance of 50 milliohms and supports a continuous current rating of 1.8 amperes. The component operates reliably within a temperature range of -40°C to +125°C, ensuring stable performance in power line filtering applications.

Feature Summary

• Single-element construction for efficient noise suppression
• Compact 0402 footprint for space-constrained designs
• High current handling capability up to 1.8A
• Wide operating temperature range for harsh environments

Applications

• Power line filtering
• Signal integrity enhancement
• EMI suppression in portable electronics

Procurement Notes

Verify the exact impedance tolerance and DC resistance specifications against the official datasheet before integration. Confirm that the 0402 package dimensions align with your PCB layout constraints. Ensure the 1.8A current rating meets the operational requirements of your specific circuit design to prevent saturation or overheating issues during peak load conditions.

Selection Notes

Select this component when a low-profile solution is required for high-current power lines. The 9-ohm impedance at 100 MHz targets common EMI frequencies. Compare the 50-milliohm DC resistance against other options to minimize voltage drop. Verify compatibility with standard reflow soldering profiles for the 0402 case size to ensure reliable assembly.

Part Context

This ferrite bead belongs to the Sigma Inductors passive product family from TE Connectivity. It is part of a series offering various impedance values in the same 0402 form factor. The product line focuses on providing reliable noise suppression for modern electronic devices requiring compact components with robust electrical characteristics.

Replacement Considerations

Cross-reference with part number 2176746-6 if a higher impedance range (9-21 ohms) is acceptable. Verify that the alternative maintains the same 0402 package and 1.8A current rating. Check for identical temperature ratings and DC resistance limits to ensure functional equivalence in the existing circuit design.
