Procurement Notes
Verify the specific impedance value and package dimensions against the official manufacturer datasheet before procurement. Confirm that the AEC-Q200 qualification status aligns with your project's automotive or industrial requirements. Ensure compatibility with standard surface-mount reflow soldering profiles during integration planning.
Selection Notes
Select this component when a 100 Ohm impedance at 100 MHz is required within a 3312 footprint. Consider the 1A current rating to ensure it does not saturate under operating conditions. Verify that the AEC-Q200 certification is necessary for the target application environment.
Part Context
This part belongs to the WE-MPSB series of ferrite beads manufactured by Wurth Elektronik. These components are engineered for high-performance noise suppression in space-constrained designs. The series supports various impedance values and current ratings to suit diverse circuit protection needs.
Replacement Considerations
Cross-reference with other Wurth Elektronik WE-MPSB variants offering similar impedance and package size. Verify equivalent AEC-Q200 qualification if substituting in automotive contexts. Ensure current handling capabilities match the original design specifications.
