The first three 60 = C digits represent significant figures and the 65 70 E RESISTANCE / TEMPERATURE CHARACTERISTICS (RTC) RTC = 15 PPM/C 49R9 RESISTANCE VALUE last digit specifies the number of zeros to = 25 PPM/C follow. = 50 PPM/C When the value is less than 100 ohms, the B TOLERANCE Initial resistance is identified by a single letter. B = 0.1% D = 0.5% F = 1.0% letter "R" is substituted for one of the significant figures to represent the decimal point. The resistance values shall follow the Standard Resistance-Tolerance Decade Table (page 11).
