Fixed Inductors Procurement Notes

Verify the specific manufacturer part number against official Wurth Elektronik documentation to confirm electrical parameters and packaging details. Ensure compliance with RoHS directives and check for any recent product change notices that may affect specifications or availability before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component for applications requiring compact shielding and high current handling in limited space. The 1008 footprint suits dense PCB layouts. Verify that the 1.9 A rated current and 3.6 A saturation current meet the specific circuit load requirements and thermal management constraints of the target application.

Fixed Inductors Part Context

This component belongs to the WE-MAPI series of SMD power inductors from Würth Elektronik. The series is characterized by its shielded design and metal alloy core technology, which offers low magnetic flux leakage and stable performance under varying load conditions compared to unshielded alternatives.

Fixed Inductors Replacement Considerations

Direct substitutes include other parts from the WE-MAPI series with matching 1.2 µH inductance and compatible 1008 footprints, such as 74438323015 or 74438323018, provided their current ratings and DCR values align with the system design.
