I Can't see a "300" in there?. The table seems to be an E80 series?.
From E24 on ...
Why can't they make some ** really useful** values like
400,500,600,700,800,900 instead of slavishly keeping to that 'log increment'
formulae. Great for always finding something that will fit *after* a design
Useless for calculating or designing anything 'up-front' such as ratio
How many people honestly prefer to use a 49.9k resistor to say a 50k
