RESISTANCE CODE
Wherever it is possible, chip resistors are provided with a resistance
code.
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.
Whether two or three significant values are represented depends on the
tolerance:
±5% requires two digits (E24 series)
−
For example: 244 = 24 × 10
4
= 240,000 = 240 kX
±1% and lower requires three digits (E24/E96 series)
