I agree.
I was at a gov contract mfgr. We were not mil spec as no one is any more. However, IF a particular procurement contractor wanted a certcain circuit built with 63/37 solders, we might eve have to get chips re-balled for them. The contractor specifies.
And they can also complain about schematic nomenclature, which is all this is about.
A good engineer knows about naming conventions and even how to investigate and learn about any encountered during any normal day. Thereafter having knowledge of yet one more standard in the recent memory zone of his brain.
Einstein said that we should not commit to memory anything that can be looked up as it clutters the mind. He was right.
But here is how inductors go.
The part marking uses an R for the decimal signifier.
A schematic, however, should never use a coded reference. We have high resolution laser printers now, so things like decimal points
are three orders of magnitude each. We are familiar with that.
Trying to garner some other country's normal usage should not be something I need to do. "4R7" is LAME when the printer AND the reader can clearly see the decimal point.
Why some dopes decided that using a comma as some kind of decimal signifier because of some lame calligraphic hack fix method for far sighted elders did has really f***ed things up. A decimal point is the same as a period... PERIOD! Keep that dumb shit in your accounting circles, but leave it out of math and engineering! Yer screwin' up the whole world.
