1-2176746-3

Overview

The 1-2176746-3 is a ferrite chip bead from the Sigma Inductors series, manufactured by TE Connectivity. It features an impedance of 120 Ohms at 100 MHz and is housed in a compact 0402 (1005 metric) surface-mount package. The component supports a maximum DC current of 800 mA with a maximum DC resistance of 150 milliohms. Designed for high-frequency noise suppression, it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides effective high-frequency noise attenuation through ferrite material properties
• Compact 0402 footprint enables dense circuit board layouts
• Low DC resistance minimizes power loss in signal paths

Applications

• High-speed data line filtering
• Power supply rail noise suppression
• RF interference mitigation in consumer electronics

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 fabrication capabilities. Ensure compatibility with standard reflow soldering profiles to maintain component integrity during assembly processes.

Selection Notes

Select this component when space constraints require a small form factor for EMI suppression. Consider the 120 Ohm impedance value relative to the target frequency spectrum for optimal filtering performance. Evaluate the 800 mA current handling capability to ensure it meets the operational load without saturation or excessive heating.

Part Context

This part belongs to the Sigma Inductors family, which focuses on passive components for signal integrity and power management. The 1-2176746-3 specifically addresses the need for reliable ferrite beads in modern electronic devices where size reduction and performance efficiency are critical design parameters.
