Overview
The Würth Elektronik 742792021 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in an 0805 (2012 metric) package. It exhibits an impedance of 22 Ω at 100 MHz and supports a rated current of 6 A. The component features a maximum DC resistance of 8 mΩ and operates within a temperature range of -55°C to +125°C. It measures 2 mm in length, 1.2 mm in width, and 0.9 mm in height. The device is qualified under the AEC-Q200 standard for automotive applications.
Feature Summary
- Provides electromagnetic interference suppression through high-current capability
- Constructed with ferrite material for effective noise attenuation
- Designed for surface mount technology integration
Applications
- Automotive electronics systems requiring AEC-Q200 compliance
- General-purpose EMI filtering in compact circuit designs
- Power line noise suppression in space-constrained environments
Procurement Notes
Verify the specific manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the received components match the specified electrical parameters and physical dimensions. Check for valid certification marks indicating RoHS compliance and AEC-Q200 qualification before integration into production lines.
Selection Notes
Select this component when high current handling is required alongside moderate impedance values in a small footprint. The 0805 case size offers a balance between power dissipation and board space efficiency. Ensure the application environment stays within the specified operating temperature limits to maintain performance stability.
Part Context
This ferrite bead belongs to the WE-CBF series, which focuses on surface-mount EMI suppression solutions. The series is characterized by its ability to handle significant currents while maintaining low DC resistance. It serves as a critical passive component for signal integrity and noise reduction in modern electronic assemblies.
Replacement Considerations
Consult official Wurth Elektronik substitution guides for verified alternatives. Cross-reference impedance curves and current ratings carefully when evaluating potential substitutes to ensure functional equivalence in the target circuit.
