2176744-4

Overview

The TE Connectivity Passive Product part number 2176744-4 is a single-channel, shielded multilayer ferrite chip bead designed for automotive grade applications. It utilizes an SMD/SMT end termination type and is housed in a 0805 (2012 metric) package with dimensions of 2.0 mm length, 1.25 mm width, and 1.0 mm height. The component exhibits an impedance of 9 Ohms at a test frequency of 100 MHz, with a tolerance range of 5 to 13 Ohms. It supports a maximum DC current of 3 Amperes and maintains a maximum DC resistance of 30 mOhms. The device operates within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive grade multilayer construction
• Shielded design for EMI suppression
• High current handling capability

Applications

• Power line filtering
• Signal integrity protection
• Automotive electronics

Procurement Notes

Verify the specific ordering suffix against official TE Connectivity documentation to ensure correct impedance tolerance and packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Check for any recent obsolescence notices or lifecycle changes directly from the manufacturer's official channels before finalizing procurement plans.

Selection Notes

Select this component when a compact 0805 footprint is required for high-current power line filtering in automotive environments. Ensure the 9 Ohm impedance at 100 MHz aligns with the target noise spectrum. Verify that the 3A current rating exceeds the operational peak current to prevent saturation. Consider the shielded nature if adjacent sensitive traces are present.

Part Context

This component belongs to the Sigma Inductors series of passive products manufactured by TE Connectivity. It is specifically engineered as a ferrite bead for suppressing electromagnetic interference in high-frequency circuits. The product line emphasizes reliability in demanding automotive and industrial settings through robust multilayer ceramic technology.
