What is the numerical difference between footprints marked with "* _M", "* _N", "* _V" and "* _L"?

P.S. I was looking any information in google, but as a result nothing.

I think they stand for

N-nominal, M-maximum, L-least

Not sure about V though.

Also if you look closely, for example, at SMD0805's N, M and L variants, you will find that they increase in size, just by little.

About why are they used when there isn't much of a difference in their sizes, read this: https://blogs.mentor.com/tom-hausherr/blog/2011/01/28/pcb-design-perfection-starts-in-the-cad-library-part-12/

  • \$\begingroup\$ Actually, thanks for asking the question. I always thought N,M and L were normal, medium and large. :) \$\endgroup\$ – Sachin Jun 19 '17 at 12:14
  • \$\begingroup\$ Also, "by eye" "V"-footprint does not many differ from "L"-footprint. It stands for "very least", I think. P.S. Became we get smarter now. :) \$\endgroup\$ – Ruslan Fatkullov Jun 19 '17 at 12:37
