2176743-3

Overview

The TE Connectivity Passive Product 2176743-3 is a single-channel, shielded multilayer chip ferrite bead designed for automotive grade 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 7 Ohms at a test frequency of 100 MHz. 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 -55°C to +155°C.

Feature Summary

• Automotive grade multilayer construction for high reliability
• Shielded design to minimize electromagnetic interference
• High current handling capability in a compact footprint

Applications

• Power line filtering in automotive electronics
• Noise suppression in high-current circuits
• Electromagnetic compatibility enhancement in vehicle systems

Procurement Notes

Verify the specific impedance tolerance and current rating against the official datasheet before integration. Confirm that the 0603 package dimensions align with the PCB layout constraints. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar variants in the Sigma Inductors series.

Selection Notes

Select this component when a low-profile, high-current ferrite bead is required for power line noise suppression. The 7 Ohm impedance at 100 MHz offers effective attenuation for common switching frequencies. The 1 A current rating suits moderate power applications. Consider the 80 mOhms DC resistance for voltage drop calculations in sensitive circuits.

Part Context

This component belongs to the Sigma Inductors ferrite bead family, specifically engineered for robust performance in demanding environments. The 2176743-3 variant is distinct from other impedance values in the same series, such as the 2176747-3 which shares the package but differs in electrical characteristics. It represents a standardized solution for EMI control in modern electronic assemblies.
