Cannot find models
¿ªÔÆÌåÓýHI, Ben. Search in the group archives, the
folders in Files which have 'z_,,,' names. You will find more
than one model. for 'potentiometer'.? That emwonder site no
longer exists. On 2025-05-15 08:40, benmeulenbeld2007

The library you want (probably) is: potentiometer_standard.lib. Note: this only contains the models, not any symbols. But they are easy enough to make to your own needs. Take time to read the model file to understand how to use it. -- Regards, Tony |

There are many (MANY!) 3-pin potentiometer symbols and models that you can find, if you really desperately need one.? I almost never use a potentiometer symbol+model, because you don't need one.? A potentiometer is literally just two resistors connected in series. ?
But as I say, there are many potentiometer symbols already.? None of them come with LTspice because they are not needed, but dozens of LTspice users have created and uploaded their own symbols over the years.? For example, if you look in either of these two locations, you will find some of them:

I found well over 100 instances of "potentiometer" in our group's Files area, and that does not include those that were written as "pot" instead of the full name "potentiometer".

That's because it is gone.? But you can find a saved copy of that website (and hopefully most of its contents) at the Wayback Machine, here:

Hi Ben,
?
You can always create your own symbol as a .asy file with the same name as the subckt. Here's the spice directive that I add to my schematic anytime I need a pot. Just make sure the .asy file is in the same folder as your schematic.

Hope that helps,
