1-2176742-4

Overview

The TE Connectivity Passive Product 1-2176742-4 is a single-channel, shielded ferrite chip bead from the BMC-Q series. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 75 Ohms at a test frequency of 100 MHz, with a tolerance range of 5 to 13 Ohms relative to the nominal value or specific variant characteristics. It supports a maximum DC current rating of 450 mA and has a maximum DC resistance of 200 mOhms. The device operates within a temperature range of -40°C to +125°C and utilizes flexible soft terminals for SMD/SMT mounting.

Feature Summary

• Shielded construction designed to minimize electromagnetic interference in compact layouts
• Automotive-grade multilayer chip bead technology ensuring reliability in demanding environments
• Flexible soft terminal design compatible with standard surface-mount assembly processes

Applications

• Embedded systems requiring high-frequency noise suppression
• Industrial automation circuits needing reliable EMI filtering
• Automotive electronics adhering to AEC-Q200 standards

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official datasheet before ordering. Confirm that the 0402 package size fits the target PCB footprint. Ensure the supplier provides documentation confirming AEC-Q200 compliance if automotive application is intended. Check for any recent product change notices regarding material or manufacturing updates.

Selection Notes

Select this component when a shielded ferrite bead is required for high-current applications up to 450 mA in a small form factor. The 75 Ohm impedance at 100 MHz makes it suitable for suppressing noise in digital signal lines. Consider the thermal operating range of -40°C to +125°C for environmental suitability. Compare DCR values to ensure voltage drop constraints are met in the circuit design.
