If not, then the gods-to-be here must create one. My colleagues and I, we are mostly into resistors/capacitors/coils/connectors/etc/etc all the stuff, and lots of nice cars and furniture filling our screen look nice, but it is actually a big motivation to go looking for 3D models on our area of interest on another sites... Just my twopence...
"Electrical" is a category. It is broad. You'd find everything from a TV, or a toaster, to an electric car under it.
For discreet components, I'd also look under "Components"
"Energy and Power" is a third place to look, but that is a bit more specific and might contain solar panels, and generators.
I'm sure new categories can/could be added.
The best option for now would be typing in the specific item you are looking for. There are pages and pages of discreet components on the site.
Why I was asking, is merely because on other site i found there were "hidden categories" which do not appear in the list, and you have to go roundabouts to add the category you need to your list. I just decided to ask before searching.
Thanks. That is somehow what I was already doing. Quite slow, however... Right now looking for sk6814mini package, faster to make my own. I will add it here when ready...
