Expressed by three-digit alphanumerics. The unit is ohm (Ω). The
first and second figures are significant digits, and the third figure
expresses the number of zeros which follow the two figures. If
there is a decimal point, it is expressed by the capital letter "R." In
this case, all figures are significant digits.
