This page is used to define the standard values used when designing circuits and what steps

Most designs are aware of the settings on this page and will adjust designs depending on selections here.

- Exact, no rounding all values are shown exactly as calculated
- E3, each decade has 3 values (10, 22 47)
- E6, each decade has 6 values (10, 15, 22, 33, 47, 68)
- E12, each decade has 12 values (10, 12, 15, 18, 22, 27, 33, 39, 47, 56, 68, 82)
- E24, each decade has 24 values
- E48, each decade has 48 values
- E96, each decade has 96 values
- E192, each decade has 192 values

Most manufactures are following these E-rows when producing resistors, capacitors and inductors.

Round resistors to | This setting is to round resistor values for most circuits designs and to define steps for Ctrl-m and Ctrl-m in many resistor input fields |

Round capacitors to | This setting is to round capacitor values for most circuits designs and to define steps for Ctrl-m and Ctrl-m in many capacitor input fields |

Round inductors to | This setting is to round inductor values for most circuits designs and to define steps for Ctrl-m and Ctrl-m in many capacitor input fields |

Step size | This setting is used to define step size for Ctrl-m and Ctrl-n in many fields |

- Most of the times you will want these settings at value that are easy to obtain and/or stock, this can by: R=E12, C=E6, L=E6
- If your want exact calculations, change all 3 settings (Resistor, capacitor and inductor) to "Exact", then your can use Series/parallel to make more exact components
- When calculations round to E values, they will adjust the other components to get as good result as possible
- when trying to find a value with
**Ctrl-m**/**Ctrl-n**, keep this page open and change step size as required
