Overview

The Würth Elektronik 742792030 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in an 0805 (2012 metric) package. It provides a nominal impedance of 30 Ohms at 100 MHz with a maximum DC resistance of 3 mOhms. The component supports a maximum DC current of 10 A and operates within a temperature range of -55°C to +125°C. It is qualified under AEC-Q200 standards for automotive applications.

Feature Summary

High current handling capability suitable for power line filtering
Automotive grade qualification ensuring reliability in harsh environments
Low DC resistance minimizes voltage drop and power loss

Applications

Automotive electronics power distribution networks
General electronic equipment EMI suppression
Battery pack circuits and battery charger inputs

Procurement Notes

Verify the specific impedance value and current rating against the official datasheet before procurement, as high-current ferrite beads may have variants with different electrical characteristics. Confirm that the 0805 package size aligns with your PCB footprint requirements. Ensure the supplier provides documentation confirming AEC-Q200 compliance if the application mandates automotive-grade certification.

Selection Notes

Select this component when designing circuits requiring significant current capacity alongside noise suppression. The low DC resistance makes it appropriate for power rails where efficiency is critical. Consider the thermal performance at full load current to ensure the operating temperature remains within the specified limits during continuous operation.
