742792602

Overview

The Würth Elektronik WE-CBF series component 742792602 is a surface-mount EMI suppression ferrite bead designed for high-current applications. It features a 0603 (1608 metric) package with an impedance of 60 Ω at 100 MHz and a maximum DC current rating of 3000 mA. The device exhibits a maximum DC resistance of 0.04 Ω and operates within a temperature range of -55°C to +125°C. It meets AEC-Q200 automotive qualification standards, ensuring reliability in demanding electronic environments.

Feature Summary

• Provides effective electromagnetic interference suppression through high-frequency impedance characteristics
• Capable of handling high direct current loads suitable for power line filtering
• Automotive-grade qualification ensures robust performance under varying thermal conditions

Applications

• Power supply output filtering in automotive electronics
• EMI suppression on data lines requiring high current capacity
• General-purpose noise reduction in compact surface-mount designs

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the selected package size aligns with the printed circuit board footprint requirements. Ensure that the operating current does not exceed the rated maximum to maintain component integrity and prevent thermal issues during operation.

Selection Notes

Select this component when space constraints necessitate a 0603 footprint while requiring significant current handling capability. The low DC resistance minimizes voltage drop across the component in power paths. Consider the AEC-Q200 certification if the application targets automotive systems or other industries requiring stringent reliability standards for passive components.

Part Context

This part belongs to the WE-CBF series from Würth Elektronik, which specializes in surface-mount ferrite beads for EMI suppression. The series offers various impedance and current ratings to suit different circuit needs. The 742792602 variant specifically addresses applications needing moderate impedance with high current throughput in a small form factor.

Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitutes. Ensure any alternative maintains equivalent impedance at 100 MHz and meets or exceeds the 3000 mA current rating. Verify package dimensions and terminal configurations to guarantee mechanical compatibility.
