I'm looking at an application note, and it contains the following in the circuit diagram:

enter image description here

What does the NS in the diagram represent? Or is this just a typo on the behalf of the manufacturer?

Edit: Further down the datasheet, this is clarified as "Not stuffed"

enter image description here

What does that mean?

  • \$\begingroup\$ I would say it means something like "Not soldered" or similar. Meaning it is not populated in this assembly. \$\endgroup\$

    \$\begingroup\$ Not Stuffed. It is in the data sheet in the BOM section. Not Stuffed means that it is not on the Board. \$\endgroup\$

NS means "No stuff". This is an assembly instruction. Nothing will be placed on the PCB for C7.

NS is yet another abbreviation along with DNL (do not load), DNP (do not populate), DNI (do not install), DNS (do not stuff), NOLOAD, OMIT.
