Also, the E192 series is used for 0.25% and 0.1% tolerance resistors. Historically, the E series is split into two major groupings: E3, E6, E12, E24 are subsets of E24. Values in this group are rounded to 2 significant figures. E48, E96, E192 are subsets of E192. Values in this group are rounded to 3 significant figures.
The 120 ohm resistor has a value ranging between 110 and 130 ohms. Following this logic, the preferred values for 10% tolerance resistors between 100 and 1,000 ohms would be 100, 120, 150, 180, 220, 270, 330 and so on (rounded appropriately); this is the E12 series shown in the table below.

The E192 series of standardized resistors. List of the values and the color codes.
4 paź 2006 · Successive values within a decade series are related (approximately) by a factor of 12 10 for the E12 Series, 24 10 for the E24 Series, 96 10 for the E96 Series and 192 10 for the E192 Series. Use of standard values is encouraged because stocking programs are designed around them.
E192 0.5% (also used for resistors with 0.25% and 0.1%). The E6 series has six values in each decade. The tolerance is ±20%.
Standard resistor values. The resistance of resistors often follows the E series. The E series consists of the E3, E6, E12, E24, E48, E96 and E192 series. A higher number correlates to a lower tolerance and a higher precision. All standard resistor values can be found in the table below.
