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