742792645

Overview

The Würth Elektronik 742792645 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in an 0603 package. It provides an impedance of 470 Ohms at a test frequency of 230 MHz and supports a maximum DC current of 1000 mA. The component features a minimum DC resistance of 150 mOhms and operates within a temperature range of -55°C to +125°C. It holds AEC-Q200 qualification for automotive reliability.

Feature Summary

• Provides high-frequency electromagnetic interference suppression through resistive loss mechanisms
• Designed for compact surface-mount integration in space-constrained circuit layouts
• Qualified for automotive applications meeting AEC-Q200 stress test standards

Applications

• Automotive electronic circuits requiring EMI filtering
• High-speed digital signal line noise suppression
• Power supply output filtering for sensitive loads

Procurement Notes

Verify the specific impedance value and current rating against your schematic requirements before ordering. Confirm that the 0603 footprint matches your PCB land pattern. Ensure the supplier provides original manufacturer documentation to guarantee component authenticity and traceability.

Selection Notes

Select this component when a low-profile SMD solution is required for broadband noise attenuation. The 470 Ohm impedance at 230 MHz targets specific high-frequency interference bands. The 1000 mA current rating suits moderate power lines where minimal voltage drop is critical.

Part Context

This part belongs to the WE-CBF family of chip beads, engineered for robust performance in demanding environments. The 0603 form factor allows for automated assembly on standard pick-and-place equipment, facilitating efficient manufacturing processes for consumer and industrial electronics.

Replacement Considerations

Check datasheets for alternative parts offering identical 0603 dimensions and comparable impedance-current characteristics. Verify that any substitute also meets AEC-Q200 standards if used in automotive contexts to ensure equivalent reliability.
