Capacitor code table
Some capacitors are only marked 0.1 or 0.01, mostly in these cases the values are given in uF. Some small capacitance capacitors can be marked with a R between numbers, f.ex. 3R9 where R is a indicator of values below 10pF and have nothing to do with resistance. 3R9 would be 3.9pF.
