1-2176743-3

Overview

The 1-2176743-3 is a ferrite chip bead from the BMC-Q series, manufactured by TE Connectivity. 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 70 ohms at 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 0.15 ohms. The operating temperature range spans from -40°C to +125°C.

Feature Summary

• High current handling capability suitable for power line applications
• Compact 0603 surface mount footprint for space-constrained designs
• Automotive-grade reliability certified under AEC-Q200 standards

Applications

• Power line filtering in automotive electronics
• EMI suppression in high-current circuits

Procurement Notes

Verify the specific suffix codes against official TE Connectivity documentation to ensure exact electrical characteristics and packaging options. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to ordering. Ensure the selected variant matches the required impedance and current ratings for the target application.

Selection Notes

Select this component when a compact ferrite bead is needed for high-current power lines requiring AEC-Q200 certification. The 0603 package offers a balance between size and current capacity. Compare the 70-ohm impedance at 100 MHz against circuit requirements to ensure effective noise suppression without excessive voltage drop across the 0.15-ohm DC resistance.
