- General-purpose noise suppression circuits
- Portable device power integrity management
Procurement Notes
Verify the specific impedance tolerance and DC current ratings against the official datasheet before finalizing design specifications. Confirm that the 0402 package dimensions align with the target PCB footprint. Ensure compliance with RoHS and REACH directives as stated in the manufacturer documentation.
Selection Notes
Select this component when space-constrained designs require effective high-frequency noise filtering on signal lines. The 900 mA current rating suits moderate load applications, while the low DC resistance minimizes voltage drop. Consider the 180-ohm impedance profile for matching specific frequency suppression requirements.
Part Context
This part belongs to the WE-CBF series of multilayer ferrite beads manufactured by Wurth Elektronik. These components are engineered for compact electronics where space efficiency and electromagnetic interference reduction are critical. The series offers various impedance values and package sizes to accommodate diverse circuit needs.
Replacement Considerations
Consult the official Wurth Elektronik datasheet for verified equivalent parts within the WE-CBF series or other compatible ferrite bead families. Ensure any substitute matches the 0402 package, 180-ohm impedance, and 900 mA current rating.
