1-2176747-3

Overview

The 1-2176747-3 is a single-channel, shielded multilayer ferrite chip bead from the BMC-Q automotive grade series. 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 100 Ohms at a test frequency of 100 MHz and supports a maximum DC current rating of 2.5 A. Its maximum DC resistance is specified at 60 mOhms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade multilayer construction designed for high reliability in vehicle electronics
• Shielded design minimizes electromagnetic interference coupling between adjacent components
• High-current capability suitable for power line filtering applications

Applications

• Power line noise suppression in automotive electronic control units
• Electromagnetic interference filtering in vehicle infotainment systems
• Signal integrity protection in automotive sensor interfaces

Procurement Notes

Verify the specific impedance value against the latest manufacturer datasheet, as distributor listings may vary. Confirm that the 0603 package size matches the target PCB footprint. Ensure the 2.5 A current rating meets the circuit requirements. Check for RoHS compliance documentation if required by the assembly process. Validate the operating temperature range suitability for the intended environment.

Selection Notes

Select this component when a compact 0603 ferrite bead is required for automotive power lines. The 100 Ohm impedance at 100 MHz targets common noise frequencies. The 2.5 A current rating distinguishes it from lower-current signal line beads. Consider the shielded feature if space constraints prevent adequate spacing from other components. Verify compatibility with standard reflow soldering profiles for SMD/SMT termination.

Part Context

This part belongs to the TE Connectivity Sigma Inductors BMC-Q series, which specializes in automotive-grade passive components. The series offers various impedance values in standardized packages like 0603 and 0402. These components are engineered to meet stringent automotive reliability standards while providing effective high-frequency noise attenuation in compact form factors.

Replacement Considerations

Cross-reference with other BMC-Q series parts for different impedance values if the 100 Ohm specification does not match the filter requirements. Verify that substitute components maintain the same 0603 footprint and 2.5 A current handling capacity. Ensure any replacement also carries automotive qualification certifications.
