Product specification Chip Resistor Surface Mount 2 8 Marking MARKING RESISTANCE CODE Wherever it is possible, chip resistors are provided with a resistance code. Table 1 Resistance value indication Indicator Tol. 5% Tol. 1% R (1) 0.001 to 9.1 0.001 to 97.6 The resistance code includes the first two or three significant digits of the resistance value (X) followed by the number of zeros; see Table 1. 0 10 to 91 100 to 976 1 100 to 910 1 to 9.76 k Whether two or three significant values are represented depends on the tolerance: 2 5% requires two digits (E24 series) - For example: 244 = 24 x 10 4 = 240,000 = 240 kX 1% and lower requires three digits (E24/E96 series) - For example: 3160 = 316 x 10 0 = 316 X 1 to 9.1 k 10 to 97.6 k 3 10 to 91 k 100 to 976 k 4 100 to 910 k 1 to 9.76 M 5 1 to 9.1 M 10 to 97.6 M 6 10 to 91 M - NOTE 1.
