742792651

Overview

The Würth Elektronik 742792651 is a surface-mount ferrite bead from the WE-CBF series, designed for EMI suppression in single-signal lines. It features a 0603 (1608 metric) package with dimensions of 1.60mm length, 0.80mm width, and 1.00mm height. The component provides an impedance of 600 Ohms at 100 MHz and supports a maximum DC current of 1A. It has a maximum DC resistance of 200 mOhms and operates within a temperature range of -55°C to +125°C. The part is AEC-Q200 qualified.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed signal lines through high impedance characteristics.
• Compact 0603 footprint enables efficient space utilization on densely populated printed circuit boards.
• Automotive-grade qualification ensures reliability and durability under demanding environmental conditions.

Applications

• High-speed data line filtering in automotive electronic control units
• EMI suppression for USB and HDMI interface circuits
• Signal integrity enhancement in consumer electronics

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact impedance and tolerance specifications. Ensure compatibility with standard reflow soldering profiles for surface-mount assembly. Confirm AEC-Q200 certification status if deploying in automotive applications. Check RoHS compliance documentation for regulatory adherence. Validate package dimensions against PCB land pattern requirements before finalizing procurement.

Selection Notes

Select this component when high attenuation is required for single-ended signals in compact spaces. The 600 Ohm impedance at 100 MHz suits broadband noise suppression. Consider the 1A current rating for power delivery constraints. The 0603 size balances performance with board area limitations. Evaluate thermal management needs given the low DC resistance and operating temperature range.

Part Context

This ferrite bead belongs to the WE-CBF family, which offers various impedance values and package sizes for EMI filtering. The series is characterized by stable performance over wide frequency ranges and temperatures. Würth Elektronik designs these components to meet stringent automotive and industrial standards, providing engineers with reliable passive filtering solutions.

Replacement Considerations

Consult official Wurth Elektronik substitution guides for verified alternatives. Cross-reference impedance curves and current ratings carefully. Ensure physical dimensions match existing footprints. Verify that any substitute maintains equivalent AEC-Q200 qualification if required for the application.
