1.2.1.2.1 Four diait resistance designation (all resistor values eaua l]. The four digit resistance
designation is applicable to
all resistance tolerances,
The nominal
resistance is identified by four digits:
the firat three digita represent significant figures and the last digit specifies the number of zeros to follows.
Vvhen the value of resistance is less than 100 ohms, or when fractional values of an ohm is required, the
“R will be substituted for one of the significant digits to represent the decimal point. When the letter “R is
used, sumeeding digits of the group represent significant figures. The resistance values designations are
shown in fables Il. Standard values for every decade will Wow the sequeuce demonstrated for”1 O to
100 decade in table Ill. Resistance values not listed in fable Ill far the appropriate resistance tolerance
will be considered as not conforming to the specification, The resistance values far tolerances V, T, A and
B may be any value within the timits specified in 3.1, but it is preferred that values be chosen from the “B
(0.1~ and “D (0.5)” mlumns of table Ill.
Although resistance tolerances “G and”~ normally require less than three significant figures to
adequately describe the true resistance value, for the purpose of this specification, the nominal value W
be three significant figures fallowed by the fourth digit to signify the number of zeros to fallow.

three digit resistance designation is applicable to tolerances G (f2.O percent) and J (+5.0 percent). The
nominal resiskmce expressed in ohms is identified by three digits the first two digita represent significant
figures and the last digit specifies the number of zeros to fallow. When the value of resistance is less than
10 ohms, or when fractional values of an ohm are required, the letter “R” will be substituted far one of the
significant digits to represent the decimal point. When the letter “R” is used, su-eding
digita of the
group represent signikant figures. The resistance value designations are shown in table IV. The
