2176742-2

Overview

The TE Connectivity 2176742-2 is a high-current ferrite chip bead designed for surface mount applications. It features a 0402 (1005 metric) package with dimensions of 1 mm length and 0.5 mm width. The component offers an impedance of 5 ohms with a tolerance range of 0 to 15 ohms. It supports a maximum DC current of 800 mA and has a maximum DC resistance of 40 mohms. The operating temperature range spans from -40°C to +125°C.

Feature Summary

• High current handling capability suitable for power line filtering
• Automotive grade construction for reliability in demanding environments
• Compact 0402 surface mount footprint for space-constrained designs

Applications

• Power line filtering in automotive electronics
• EMI suppression in high-current circuits
• Signal integrity management in compact mobile devices

Procurement Notes

Verify the specific impedance tolerance variant required, as the part number covers a range of 0 to 15 ohms. Confirm availability status through authorized distributors, as stock levels may vary by region. Ensure the selected variant meets the specific DC current rating of 800 mA for your application design.

Selection Notes

Select this component when high current capacity is critical alongside EMI suppression. The 0402 package size allows for dense PCB layouts. Consider the low DC resistance of 40 mohms to minimize voltage drop in power paths. Verify that the 5 ohm nominal impedance aligns with the target noise frequency spectrum for effective filtering performance.

Part Context

This component belongs to the Sigma BMC-Q series of ferrite beads, which are engineered for automotive and industrial applications. The series emphasizes high current ratings and robust thermal performance within small form factors, addressing the need for efficient noise suppression in modern electronic systems without compromising board real estate.

Replacement Considerations

Direct substitutes include other TE Connectivity parts within the same BMC-Q family, such as 1-2176742-1 or 2-2176742-2, depending on the exact impedance requirement. Ensure any replacement maintains the 0402 package dimensions and meets the 800 mA current rating to preserve circuit functionality.
