2176742-1

Overview

The TE Connectivity 2176742-1 is a single-channel power line ferrite bead in a 0402 (1005 metric) surface-mount package. It exhibits an impedance of 0 Ohms at 100 MHz and supports a maximum DC current rating of 800 mA. The component features a maximum DC resistance of 40 mOhms. It operates within a temperature range of -40°C to +125°C, with physical dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height.

Feature Summary

• Designed for high-current power line applications
• Automotive-grade multilayer chip bead construction
• Shielded configuration to minimize electromagnetic interference

Applications

• Power supply filtering in automotive electronics
• Noise suppression on high-current data lines
• EMI reduction in compact mobile device circuits

Procurement Notes

Verify the specific impedance value against the official datasheet, as some sources list this part number with 0 Ohms while others may reference different variants within the same series. Confirm RoHS compliance status and ensure the 0402 footprint matches your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a low-impedance path is required for high-current signals up to 800 mA. The 0402 package suits space-constrained designs. Ensure the application environment stays within the -40°C to +125°C operating range and that the 40 mOhm DCR meets voltage drop specifications.

Part Context

This part belongs to the Sigma Inductors ferrite bead family from TE Connectivity. It is categorized under passive products specifically designed for EMI suppression. The 2176742-1 model represents a specific impedance variant within the broader BMC-Q series of automotive-grade components.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering similar 800 mA ratings and low DC resistance. Verify that substitute parts maintain the same automotive qualification standards and thermal performance characteristics.
