LTSpice Tips – Component Values

When specifying the values of components, a few tips:

  • You specify the value for the part, not the units.  Example: for a 10 ohm resistor, enter “10” for the value, not “10 ohm”.
  • Make use of metric prefixes (listed below) to specify value.  Example: for a 1000 ohm resistor, you can enter “1000” or “1k”.
  • The metric prefixes are not case sensitive

Valid metric prefixes in LTSpice (from Linear’s Getting Started Guide):


The most common error is to use “M” for megaohms.  You have to use “Meg” instead.
