742792312

Overview

The Würth Elektronik 742792312 is a surface-mount ferrite bead from the WE-CBF series, designed for EMI suppression in single-signal lines. It features a 1210 (3225 metric) package with dimensions of 3.20mm x 2.50mm x 1.50mm maximum height. The component provides an impedance of 65 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 3A. It has a maximum DC resistance of 30 mOhms and operates within a temperature range of -55°C to +125°C. The device is AEC-Q200 qualified for automotive applications.

Feature Summary

• Provides effective electromagnetic interference suppression for high-current signal lines
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact surface-mount design suitable for space-constrained PCB layouts

Applications

• Automotive electronics systems requiring EMI filtering
• High-speed data line protection in consumer electronics
• Power supply input/output filtering in industrial equipment

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as cut tape or reel quantities. Confirm that the AEC-Q200 qualification status meets your project's automotive compliance requirements. Check the latest datasheet for any updates on recommended soldering profiles and reflow temperature limits to ensure process compatibility.

Selection Notes

Select this component when a low DC resistance and high current handling capability are required alongside moderate impedance values. The 1210 package offers a balance between current capacity and board space efficiency. Ensure the operating environment stays within the specified -55°C to +125°C range to maintain performance stability and longevity.

Part Context

This part belongs to the WE-CBF family of chip ferrite beads manufactured by Würth Elektronik. The series is characterized by its ability to handle significant DC currents while providing consistent impedance characteristics across a wide frequency spectrum. These components are widely used in modern electronic designs where signal integrity and noise suppression are critical.

Replacement Considerations

Consult official Wurth Elektronik documentation for verified cross-reference part numbers. Ensure any substitute maintains the same 1210 footprint, 65 Ohm impedance at 100 MHz, and 3A current rating. Verify that alternative components also meet AEC-Q200 standards if automotive application is required.
