1-2176743-4

Overview

The TE Connectivity 1-2176743-4 is an automotive-grade multilayer chip ferrite 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 80 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 150 mOhms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade construction suitable for demanding environments
• High-current capability for power line filtering
• Shielded design to minimize electromagnetic interference

Applications

• Power supply input filtering
• Automotive electronic circuits
• High-frequency noise suppression in power lines

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with TE Connectivity or authorized distributors before procurement. Confirm that the 0603 package footprint matches your PCB layout requirements. Ensure the 1 A current rating and 80 Ohm impedance specifications align with your circuit's noise suppression needs. Check for any lead-free soldering process compatibility if required by your manufacturing standards.

Selection Notes

Select this component when a compact 0603 form factor is required for automotive power line filtering. The 1 A current rating makes it suitable for moderate power applications where space is constrained. Consider the 150 mOhm DCR for voltage drop calculations in low-voltage systems. The wide operating temperature range ensures reliability in harsh automotive environments compared to standard industrial components.

Part Context

This part belongs to the BMC-Q series of multilayer chip ferrite beads from TE Connectivity. The series is specifically engineered for automotive electronics, offering robust performance under thermal and mechanical stress. It complements other passive components in power management circuits by providing effective high-frequency attenuation without significant DC resistance loss.

Replacement Considerations

Direct substitutes must match the 0603 package, 80 Ohm impedance at 100 MHz, 1 A current rating, and automotive grade certification. Verify equivalent DCR and temperature ratings to ensure circuit compatibility. Cross-referencing with other manufacturers' automotive ferrite bead catalogs is recommended for availability.
