I want to use the 744873470 inductor, but I am confused about how to place it.

This is the datasheet of it.enter image description here

This is the footprint in my Altium design and the 3D view.

And this is the place direction of Eurocircuits, they want to place in this way because the PCB data does not contain any visible orientation information for this component. enter image description here I'm wondering how should I place this component correctly?

This is the model on Mouser. enter image description here

This is my schematic. enter image description here New footprint enter image description here

The assembly orientation of this particular part doesn't matter as long as the pads match up with the component.

I'm not sure why you'd want to go and change the pin numbers on the part from the datasheet designations. That seems like it is inviting possible errors. Or maybe it is an error. I suggest you follow the diagrams:

  • \$\begingroup\$ Hi, I made no modifications to the pads, this is a direct import from Mouser. I attached a picture in my question, is this a wrong model in itself? \$\endgroup\$ Commented Jul 17 at 12:58
  • \$\begingroup\$ @Sam Nice symbol from Mouser. 1 is 3 and 2 is 4. etc. And the symbol doesn't tell you where the coils are connected and where the dots are. Is it wrong? Hard to tell. Suggest you throw that crud out and make your own. You understand my point that when it is correct you can rotate the inductor 180° and it will work the same? \$\endgroup\$ Commented Jul 17 at 14:13
  • \$\begingroup\$ I think the symbol from Mouser is not correct. The number of the pad is wrong, I download a new footprint and post in my question \$\endgroup\$ Commented Jul 17 at 14:47
  • \$\begingroup\$ Fix the symbol in the schematic then we can talk. You should be able to see the dots and the coils without opening up a datasheet pdf to find pin numbers. \$\endgroup\$ Commented Jul 17 at 15:12
