742792114

Overview

The Würth Elektronik 742792114 is a WE-CBF series surface-mount EMI suppression ferrite bead in a 1206 (3216 metric) package. It exhibits an impedance of 50 ohms at 100 MHz and supports a maximum DC current of 3 A with a maximum DC resistance of 30 mΩ. The component operates within a temperature range of -55°C to +125°C, complies with AEC-Q200 automotive standards, and features molded construction with reliable Ni-Sn electrodes.

Feature Summary

• Molded multi-layer construction for robust mechanical stability
• AEC-Q200 qualified for automotive reliability requirements
• Compatible with standard reflow soldering processes

Applications

• Automotive electronic circuit protection
• EMI suppression in signal lines
• Power supply filtering applications

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical parameters, as variations exist within the WE-CBF family. Confirm RoHS and REACH compliance status directly from the manufacturer's documentation before integration into regulated assemblies.

Selection Notes

Select this component when a 1206 footprint is required for high-current EMI filtering. Ensure the 50-ohm impedance at 100 MHz aligns with target noise frequencies. Verify that the 3 A current rating exceeds the application's peak operational current to prevent saturation.

Part Context

This part belongs to the WE-CBF series of SMD EMI suppression ferrite beads. The series offers various impedance values and current ratings across multiple standard package sizes, providing designers with flexible options for board-level noise mitigation in compact electronic designs.

Replacement Considerations

Cross-reference with other Wurth WE-CBF variants or equivalent industry ferrite beads in the 1206 package. Ensure substitute parts match the 50 Ω @ 100 MHz impedance and 3 A current handling capabilities.
