2176742-3

Overview

The TE Connectivity Passive Product component 2176742-3 is a single-channel ferrite bead designed for surface-mount applications. It utilizes the BMC-Q series architecture within a compact 0402 (1005 Metric) package, measuring 1.0 mm in length and 0.5 mm in width. The device provides an impedance of 7 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current rating of 800 mA while maintaining a low maximum DC resistance of 40 mOhms. This component is rated for AEC-Q200 standards.

Feature Summary

• High-current handling capability suitable for power line filtering applications
• Automotive-grade reliability compliant with AEC-Q200 qualification standards
• Compact surface-mount footprint optimized for dense PCB layouts

Applications

• Power line noise suppression in automotive electronic systems
• EMI filtering for high-current signal paths
• Common mode noise attenuation in compact circuit boards

Procurement Notes

Verify the specific ordering suffix to confirm the exact impedance value and tolerance, as variations exist within this product family. Ensure the selected variant matches the required DC current rating and package dimensions for your design. Confirm that the AEC-Q200 qualification status meets your project's automotive or industrial reliability requirements before finalizing procurement.

Selection Notes

Select this component when a low-profile ferrite bead is required for high-current power lines. The 0402 package offers space efficiency, while the 800 mA rating prevents saturation. Consider the 7 Ohm impedance at 100 MHz for target noise frequencies. Verify thermal performance under continuous load conditions to ensure the low DC resistance minimizes power loss and heat generation in the circuit.

Part Context

This part belongs to the BMC-Q series of multilayer chip beads from TE Connectivity. These components are engineered specifically for automotive and demanding industrial environments. The series emphasizes robust construction and stable electrical characteristics across wide temperature ranges, providing reliable electromagnetic interference suppression for sensitive electronics.

Replacement Considerations

Compatible substitutes include other AEC-Q200 qualified ferrite beads in the 0402 package with similar 7 Ohm impedance and 800 mA current ratings. Ensure cross-reference parts match the physical dimensions and terminal configuration for direct board replacement.
