1-2176745-1

Overview

The TE Connectivity Passive Product 1-2176745-1 is a single-line power line ferrite bead in a 1206 (3216 Metric) surface-mount package. It exhibits an impedance of 31 Ohms at 100 MHz and supports a maximum current rating of 3A with a maximum DC resistance of 70mOhm. The component operates within a temperature range of -40°C to +125°C and features automotive qualification.

Feature Summary

• Designed for high-current power line applications
• Automotive qualified construction
• Single-line configuration for EMI suppression

Applications

• Automotive electronics circuits
• Power line filtering
• EMI suppression in high-current paths

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before integration, as these parameters are critical for circuit performance. Confirm that the 1206 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly.

Selection Notes

Select this component when automotive-grade reliability is required for power lines carrying up to 3A. The 31 Ohm impedance at 100 MHz provides effective noise attenuation for common switching frequencies. The low DC resistance minimizes power loss and voltage drop in the supply path compared to higher-resistance alternatives.

Part Context

This ferrite bead belongs to the Sigma Inductors passive product family from TE Connectivity. It is designed to suppress electromagnetic interference in sensitive electronic circuits. The component utilizes a shielded design to contain magnetic fields while providing effective broadband noise reduction in compact surface-mount form factors suitable for modern PCB layouts.
