Overview
The Würth Elektronik 782219301 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 0201 (0603 metric) package and provides an impedance of 300 Ω at 100 MHz. The component supports a maximum DC current of 400 mA with a maximum DC resistance of 0.61 Ω. It is designed for general electronic equipment and holds AEC-Q200 qualification.
Feature Summary
- Provides effective electromagnetic interference suppression in compact surface-mount form factors
- Engineered to meet automotive reliability standards through AEC-Q200 qualification
- Designed for integration into general electronic equipment circuits
Applications
- General electronic equipment signal line filtering
- Automotive electronics requiring AEC-Q200 compliant components
- High-frequency noise suppression in compact PCB layouts
Procurement Notes
Verify the manufacturer part number 782219301 against official Wurth Elektronik documentation to confirm specifications. Ensure compatibility with 0201 footprint requirements and 400 mA current ratings. Check for RoHS compliance status as indicated in official datasheets before procurement.
Selection Notes
Select this component when space-constrained designs require SMT ferrite beads with defined impedance characteristics. The 0201 package suits high-density boards, while the 400 mA rating fits low-power signal lines. Confirm thermal performance and impedance curves match specific frequency noise profiles.
Part Context
This component belongs to the WE-CBA series of surface-mount ferrite beads manufactured by Würth Elektronik. The series focuses on providing EMI suppression solutions in small footprints suitable for modern miniaturized electronics. The 782219301 variant specifically targets applications needing standardized 0201 dimensions with verified automotive-grade reliability.
Replacement Considerations
Cross-reference with other 0201 ferrite beads offering similar 300 Ω impedance and 400 mA current handling. Verify that alternative parts maintain AEC-Q200 qualification if automotive use is required. Ensure physical footprint and terminal configurations are compatible with existing PCB layouts.
