Overview
The TE Connectivity 2176743-8 is an automotive-grade multilayer ferrite chip bead designed for high-current power line 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 30 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 80 mOhms. The device operates within a temperature range of -40°C to +125°C and is shielded.
Feature Summary
- Automotive-grade construction compliant with AEC-Q200 standards
- High-current capability suitable for power line filtering
- Shielded design to minimize electromagnetic interference
Applications
- Power line noise suppression in automotive electronics
- EMI filtering for high-current circuits
- Signal integrity protection in compact PCB layouts
Procurement Notes
Verify the specific impedance value against official datasheets, as distributor listings may vary between 26 Ohms and 30 Ohms for this part number. Confirm RoHS compliance status and ensure the selected variant matches the required 0603 package dimensions. Check for any specific ordering suffixes that might indicate different tolerances or packaging options before finalizing procurement.
Selection Notes
Select this component when space-constrained designs require a 0603 footprint for power line filtering. Ensure the application current does not exceed 1 A to maintain performance. Verify that the 30 Ohm impedance at 100 MHz aligns with the target noise frequencies. Consider the 80 mOhm DCR impact on voltage drop in low-voltage circuits.
Part Context
This ferrite bead belongs to the Sigma Inductors BMC-Q series, which focuses on automotive reliability. It is part of a family of multilayer chip beads designed to replace traditional wire-wound components in modern surface-mount assemblies. The series emphasizes high current handling and consistent impedance characteristics across wide temperature ranges.
Replacement Considerations
Cross-reference with other 0603 ferrite beads offering similar 1 A current ratings and 30 Ohm impedance. Ensure substitute parts meet AEC-Q200 requirements if used in automotive contexts. Verify compatible mounting pads and thermal characteristics for direct replacement.
