742861160

Overview

The Würth Elektronik 742861160 is a surface-mount ferrite bead from the WE-CBF HF series, designed for high-frequency EMI suppression. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 600 Ohms at 100 MHz and supports a maximum DC current of 200 mA. It has a maximum DC resistance of 0.9 Ohms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Modified internal layout increases effective electromagnetic interference suppression performance
• High-frequency design optimized for signal line protection in compact spaces
• AEC-Q200 qualified for automotive electronics reliability standards

Applications

• Signal line filtering in automotive electronic systems
• EMI suppression for high-speed data interfaces
• Noise reduction in portable consumer electronics

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the 0603 footprint matches the target PCB layout. Ensure the selected supplier provides traceable documentation for AEC-Q200 compliance if used in automotive applications. Check for RoHS and REACH certification status to meet regulatory requirements.

Selection Notes

Select this component when space constraints require a 0603 package but higher frequency suppression is needed compared to standard ferrites. The 200 mA current rating suits low-power signal lines rather than power rails. Consider the 600 Ohm impedance at 100 MHz to ensure it aligns with the noise spectrum of the application. Verify thermal stability requirements against the 125°C maximum operating temperature.

Part Context

This part belongs to the WE-CBF HF (High Frequency) series, which utilizes modified internal layouts to enhance suppression capabilities. It complements other WE-CBF variants by offering specialized performance for high-speed digital circuits where standard ferrites may be insufficient.

Replacement Considerations

Direct substitutes include other 0603 ferrite beads with similar 600 Ohm impedance at 100 MHz and 200 mA ratings. Verify package dimensions and terminal compatibility before substitution.
