Feature Summary

• Multilayer construction for effective EMI suppression
• High current handling capability
• Automotive grade qualification

Applications

• Power supply line filtering
• Automotive electronics
• EMI suppression in high-current circuits

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet before integration. Confirm that the package dimensions align with your PCB footprint requirements. Ensure the selected variant meets all necessary automotive reliability certifications for your target application environment.

Selection Notes

Select this component when high current capacity is required alongside significant impedance at 100 MHz. The multilayer design offers compact size advantages over traditional beads. Verify thermal performance under maximum load conditions to ensure stable operation within the specified temperature range.

Part Context

This part belongs to the WE-MPSB series, which focuses on multilayer power suppression solutions. These components are engineered to replace discrete inductors or standard ferrite beads where space constraints and high current ratings are critical factors in the circuit design.

Replacement Considerations

Check for direct substitutes within the WE-MPSB series that match the 550 Ohm impedance and 4A rating. Ensure any alternative maintains the same AEC-Q200 qualification status if automotive compliance is mandatory.
