RESISTANCE VALUE
Three or four digits are used with all leading digits significant. Four digits
are used for 1% tolerance or lower, otherwise three digits are used. The last
digit specifies the number of zeros to add. The letter "R" is used to
represent the decimal for fractional ohmic values. Example: 5R6 is 5.6
ohms.
