2176742-4

Overview

The TE Connectivity 2176742-4 is a single-channel, shielded ferrite chip bead from the BMC-Q series, designed for high-current applications. 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 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 800 mA and has a maximum DC resistance of 40 mOhms. The device operates within a temperature range of -40°C to +125°C and utilizes flexible soft terminals.

Feature Summary

• Automotive-grade multilayer construction certified to AEC-Q200 standards
• Shielded design to minimize electromagnetic interference
• Flexible soft terminals for enhanced mechanical reliability

Applications

• Power line filtering in automotive electronics
• High-current signal integrity management
• EMI suppression in compact SMD layouts

Procurement Notes

Verify the specific impedance tolerance variant required, as the BMC-Q series offers ranges such as 5-13 Ohms for this part number. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the 0402 footprint matches the target PCB design constraints. Check for any regional distribution restrictions that may affect availability.

Selection Notes

Select this component when a low-profile 0402 ferrite bead is needed for power lines carrying up to 800 mA. The 9 Ohm impedance at 100 MHz provides effective noise attenuation without excessive voltage drop. The wide operating temperature range suits harsh automotive environments. Consider the shielded feature if adjacent sensitive traces require isolation.

Part Context

This part belongs to the Sigma Inductors BMC-Q series by TE Connectivity Passive Product. It is categorized under Ferrite Beads and Chips within the broader passive components portfolio. The series is specifically engineered for automotive applications requiring robust performance under high current conditions.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering similar 800 mA ratings and ~9 Ohm impedance. Verify terminal compatibility and thermal characteristics against alternatives.
