- Engineered for space-constrained designs using a compact 0402 surface-mount footprint
- Capable of handling rated currents up to 250 mA while maintaining low DC resistance
Applications
- High-speed digital signal line filtering
- EMI suppression in portable electronic devices
- Noise reduction in automotive electronics systems
Procurement Notes
Verify the specific ordering suffix to ensure correct packaging format, such as tape and reel or cut tape, as these affect handling procedures. Confirm that the AEC-Q200 qualification status meets your project's reliability requirements. Check the latest datasheet for any updates regarding RoHS compliance and material declarations before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits requiring significant attenuation of high-frequency noise in tight spaces. Ensure the operating current remains below the 250 mA rating to prevent saturation. Consider the 600 Ohm impedance value relative to the target frequency spectrum to validate filtering effectiveness against system-specific EMI profiles.
Part Context
This part belongs to the WE-CBF series of SMD EMI suppression ferrite beads manufactured by Würth Elektronik. The series offers various impedance and current ratings across multiple standard package sizes, allowing designers to balance performance and board space efficiently.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Cross-referencing requires matching impedance values, current ratings, and physical dimensions to ensure compatibility without redesigning the PCB layout.
