Components Library and Circuits
For all of these components, place the subcircuit and the component in their respective folders, then restart LTspice. The component will then show up as a menu selection.
An LTspice Standard Library Replacement
The whole library replacement / addition as one zip file Place in \lib\cmp as a replacement, or carefully extract what you need (Suggested)
A Large LTspice Folder from Bordodynov
Bordodynov has kindly shared his entire LTspice folder with tons of parts and examples.
The whole library replacement with additions plus tons of examples as one zip file - about 33 MEG.
This entire zip file has been expanded so you can view the contents, and it will be available to search engines.
You start by opening folders here:
LTspiceIV-library (Directory Style - Drill Down)
LTspiceIV-examples (Directory Style - Drill Down)
LTspiceIV-library Library Listing Expanded (over 1 Meg)
LTspiceIV-library Examples Listing Expanded (over 1 Meg)
A note on portability of these "permanent" LTspice Components:
Many comments are made about the lack of portability of creating these permanent parts in LTspice. The approach preferred by most is to include the symbols and SPICE models directly in the folder of the schematic you are testing. PLEASE NOTE that using this method to create permanent LTspice models does not prevent this portability! Create your permanent part, or add the parts from the list below. When you share this schematic with others, or use it on a computer that does not have this component, just copy the 'asy' file and its associated SPICE reference to the 'asc' file you are providing to the foreign computer.
In this way, you can have the best of both worlds: You can build up a permanent library of useful parts, immediately accessible when you create a circuit AND you have portability!

NEW UPDATED VERSION
Roberto Hugo Rodríguez Zubieta in 2005 created this executable, that provides a large number of extra components. First, backup your existing /lib/cmp directory at a minimum, and you may find it easy to just zip your entire /lib directory down. This executable will overwrite /Lib/Cmp with many more components that is based a dated version of the LTspice originals. The existing files are put into a folder /Lib/Cmp/Original. The dated version is not a problem. From LTspice, under 'Tools', selecting 'Sync Release' will restore all of the new models in the latest libs from LTspice. (At least every one I could see, using a Diff program.) Plus now you have many more.
The rest includes more than 90 files in the format *. sub, to denote that they contain subcircuits of devices or *. lib, for the files that contain families of components. This information is added to the folder /sub and it doesn't overwrite any original data. To the folder /sym is added several subfolders with files corresponding to more than 400 symbols.
In the folder \examples\LtSpicePlus, there are more of 600 clever examples to be run, these are mainly in format *. asc, although there are also some few ones in format *. cir; plus in this collection there are also near 100 symbols in format *. asy.
The install is in Spanish! The product result is in English. If you come across some 'Replace' options, etc, be prepared to Google some Spanish words to make sure you know what you are selecting. It's a 3.5MEG download.
If you don't speak Spanish, try those instructions:
- say "Aceptar" (Accept).
- Point the "Carpeta de Destino" (Destiny Folder) parameter at your LTSpice install-folder, normally it is C:\Program Files\LTC\LTSpice IV, but it will vary (e.g. in a Portuguese version of Windows it will be 'C:\Arquivos de Programas'...).
- If it complains about "Los siguinentes ficheros ya existen" (The following files already exist), choose what you consider to be most adequate: Sí/No (Yes/No), "Sí a todo/No a todo" (Yes to replace all/Replace nothing at all) or "Renombrar" (Rename). It's your choice, I'd say "yes" after checking if filesizes are similar (i.e. a library you already have).
- The extraction will run, it takes a while (lots of files). If finishes correctly and doesn't give any error, probably all went well, try some examples just to be sure.
Roberto has Spanish documentation and tutorials using LTspice at Precisión, guía para desarrollos con Ltspice.
