1-2176742-2

Overview

The TE Connectivity Passive Product 1-2176742-2 is a single-line power line ferrite bead chip component from the BMC-Q series. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length and 0.5 mm width. The device provides an impedance of 60 Ohms at 100 MHz and supports a maximum DC current rating of 600 mA. Its maximum DC resistance is 150 mOhm, with a tolerance range of ±25%. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Designed for high-current power line applications in compact footprints
• Provides effective electromagnetic interference suppression at 100 MHz
• Utilizes robust ceramic construction for thermal stability

Applications

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

Procurement Notes

Verify the specific impedance value and current rating against the target circuit requirements before integration. Confirm that the 0402 package dimensions align with the PCB land pattern design. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the manufacturer datasheet for soldering profile recommendations to maintain component integrity during assembly processes.

Selection Notes

Select this component when space constraints require a 0402 footprint but higher current handling than standard signal beads allows. The 600 mA rating distinguishes it from lower-current variants in the same series. Consider the 60 Ohm impedance characteristic for the specific frequency band requiring attenuation. Evaluate the 150 mOhm DC resistance impact on voltage drop in low-voltage power rails.

Part Context

This part belongs to the Sigma Inductors BMC-Q series, which focuses on miniaturized passive components for modern electronics. The 1-2176742-2 designation identifies a specific impedance and current variant within this broader family.
