Standard Resistor Values: 1%

---

Example: Calculations indicate the need for a 355 kΩ 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 kΩ.

Standard resistor values are calculated using the simple formula given below. Round the results to the proper number of significant figures (3 for 1% and 2%, 2 for 5% and 10%). As the chart at the right shows (created in Excel), plotting the values on a logarithmic scale results in a straight line.
