1-2176743-0

Overview

The TE Connectivity 1-2176743-0 is a single-channel ferrite chip bead from the BMC-Q series, designed for automotive-grade applications. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 31 ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 0.08 ohms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade multilayer construction suitable for high-reliability environments
• High-current capability optimized for power line filtering applications
• Shielded design to minimize electromagnetic interference

Applications

• Automotive electronic circuit noise suppression
• Power supply input/output filtering
• High-frequency signal integrity protection in compact PCB layouts

Procurement Notes

Verify the specific impedance value against the official datasheet, as distributor listings may vary slightly between 30 and 31 ohms for this part number. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability can be restricted. Ensure the ordering suffix matches the required packaging format, such as cut tape or reel quantities, prior to purchase.

Selection Notes

Select this component when a 0603 footprint is required for automotive-grade EMI suppression. The 1 A current rating makes it suitable for power lines where higher dissipation is needed compared to standard beads. Verify that the 31 ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Ensure the PCB layout accommodates the specified thermal and electrical constraints for optimal performance.

Part Context

This part belongs to the Sigma Inductors BMC-Q series, which focuses on high-current ferrite beads for automotive electronics. The series is characterized by its robust construction and ability to handle significant DC bias currents while maintaining effective noise attenuation. It complements other passive components in complex automotive power management systems.

Replacement Considerations

The 2176743-9 is a verified substitute offering similar 0603 packaging and 1 A current handling, though it specifies a 30 ohm impedance. Verify compatibility regarding exact impedance requirements and tolerance levels before substitution.
