Procurement Notes
Verify the specific datasheet version to confirm exact impedance tolerances and thermal characteristics. Ensure the ordering part number matches the required package dimensions and pin configuration. Confirm compliance requirements such as RoHS and REACH status before finalizing procurement specifications.
Selection Notes
Select this component when high current handling up to 5A is required alongside significant impedance at 25 MHz. The five-hole architecture allows for greater magnetic path efficiency compared to single-hole beads. Verify that the PCB footprint accommodates the 8.50 mm x 4.65 mm dimensions and 5.50 mm height constraint.
Part Context
This component is part of the WE-SUKW series from Wurth Elektronik, designed specifically for SMD applications requiring robust EMI filtering. The series emphasizes high current capacity and reliable soldering through specialized pad designs, catering to industries demanding strict quality and performance standards.
Replacement Considerations
Cross-reference with other Wurth Elektronik WE-SUKW variants or comparable five-hole SMD ferrites from other manufacturers. Ensure replacement parts match the 580 Ohm impedance at 25 MHz and 5A current rating. Verify physical footprint compatibility and AEC-Q200 certification if used in automotive contexts.
