1-2176742-0

Overview

The TE Connectivity 1-2176742-0 is a single-line ferrite bead designed for power line filtering in the 0402 (1005 Metric) surface-mount package. It exhibits an impedance of 36 Ohms at 100 MHz and supports a maximum DC current rating of 600 mA. The component operates within a temperature range of -40°C to +125°C and features a 1LN configuration.

Feature Summary

• Provides electromagnetic interference suppression for power lines
• Automotive-grade construction suitable for harsh environments
• Compact 0402 footprint for space-constrained designs

Applications

• Automotive electronic systems
• Power line noise filtering
• Embedded circuit protection

Procurement Notes

Verify the specific impedance value against official datasheets, as conflicting public records list 36 Ohms and 50 Ohms for similar part numbers. Confirm the current rating is 600 mA or 800 mA based on the exact revision. Ensure the package matches the 0402 metric standard before integration.

Selection Notes

Select this component when automotive-grade EMI suppression is required in minimal board space. The 0402 size limits thermal dissipation compared to larger packages. Verify that the 600 mA current rating meets the application's peak load requirements without saturation.

Part Context

This ferrite bead belongs to TE Connectivity’s Sigma Inductors passive product line. It is engineered for high-reliability applications, specifically targeting the automotive sector where stability across wide temperature ranges is critical for system integrity.

Replacement Considerations

Cross-reference with 1-2176742-1 for potential impedance variations. Verify pinout compatibility and physical dimensions before substituting to ensure proper fit in existing footprints.
