Standard Resistor Values

Standard Resistor values

Standard base resistor values are given in the following tables for the most commonly used tolerances (1%, 5%, 10%), along with typically available resistance ranges. To determine values other than the base, multiply the base value by 10, 100, 1 000 or 10 000.

Example:
Calculations indicate the need for a 355 kW resistor and a tolerance of 1% .

Look in the 1% table and select the 35.7 value (the nearest available standard value). Multiply by 10 000 to convert to 357 kW.
1% Standard ValuesDecade multiples are available from 10.0 W through 1.00 MW(also 1.10 MW, 1.20 MW, 1.30 MW, 1.50 MW, 1.60 MW, 1.80 MW, 2.00 MW and 2.20 MW)
