Resistance Code:
Expressed in ohms. A three digit code where the first
two digits are significant figures, and the third digit indicates the number
of zeros that follow these figures (i.e., 100 = 10Ω; 101 = 100Ω; 102 = 1,000Ω;
103 = 10,000Ω; 105 = 1,000,000Ω ).
See table for standard resistance values.
