2176746-2

Overview

The TE Connectivity 2176746-2 is a single-line power line ferrite bead in the BMC-Q series, housed in a compact 0402 (1005 Metric) surface-mount package. It provides an impedance of 5 Ohms at 100 MHz with a maximum DC current rating of 1.8 A and a maximum DC resistance of 50 mOhm. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Designed for high-current power line noise suppression applications
• Automotive-grade reliability suitable for harsh environments
• Compact footprint enables dense circuit board layouts

Applications

• Power supply input filtering
• Noise suppression on data lines
• EMI reduction in automotive electronics

Procurement Notes

Verify the specific impedance value against project requirements, as datasheet references vary between 5 Ohms and 100 Ohms for this part number. Confirm the manufacturer lead time of approximately 20 weeks during planning. Ensure the selected variant matches the required current rating and tolerance specifications for the target application.

Selection Notes

Select this component when space constraints require a 0402 package but higher current handling than standard signal beads allows. The 1.8 A rating supports power rail filtering where lower-current alternatives would saturate. Verify that the 5 Ohm impedance at 100 MHz aligns with the targeted noise frequency spectrum.

Part Context

This ferrite bead belongs to the Sigma BMC-Q series, which focuses on automotive-grade passive components. The series offers various impedance values in small form factors, balancing EMI performance with physical size limitations common in modern electronic assemblies.

Replacement Considerations

Cross-reference with other 0402 ferrite beads rated for 1.8 A and 5 Ohms impedance. Ensure substitute parts meet the same -40°C to +125°C operating temperature range and automotive qualification standards.
