742792609

Overview

The Würth Elektronik 742792609 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a 0603 (1608 metric) package. It provides an impedance of 30 Ω at 100 MHz and supports a DC current rating of 3 A. The component features a low DC resistance of 0.04 Ω and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed for direct surface mounting on printed circuit boards
• Provides effective electromagnetic interference suppression with low DC resistance
• Complies with AEC-Q200 automotive qualification standards

Applications

• EMI suppression in compact electronic circuits
• Automotive electronics requiring AEC-Q200 compliance
• High-current signal line filtering

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the 0603 package dimensions align with the target PCB footprint. Ensure the selected supplier provides documentation confirming AEC-Q200 certification status for this specific part number.

Selection Notes

Select this component when space constraints require a 0603 footprint while maintaining a 3 A current handling capability. The 30 Ω impedance at 100 MHz makes it suitable for high-frequency noise attenuation. Consider the low DC resistance for minimizing voltage drop in power-sensitive applications.

Part Context

This ferrite bead belongs to the WE-CBF series, which specializes in SMD EMI suppression components. The series offers various impedance and current ratings across multiple standard packages, including 0402, 0603, and 0805, to support diverse design requirements for noise filtering in modern electronics.

Replacement Considerations

Cross-reference with other Wurth Elektronik WE-CBF parts in the 0603 package if different impedance or current ratings are required. Verify compatibility with existing PCB layouts before substituting with components from other manufacturers.
