Added:
https://www.seventransistorlabs.com/Modeling/SPICE/HI0603P600R_NL.ckt
with comparison plot:
https://www.seventransistorlabs.com/Modeling/Images/HI0603P600R_Overlay.jpg

Corrected the MI1206L391R_NL.ckt part and added comparison plot as well.

I suspect the error in these parts may simply be error in the flux calculation in my generating tool.  I may write a page about these some day to show how this works.

A reader e-mailed that the "^" operator doesn't work in LTspice.  I'm in the process of changing the syntax in all models to use PWR(), * or SQRT().  (Well, I've changed them already, that's the easy part, but I want to actually check them before updating the site...)  If you are using LTspice, you may want to give this a check.

Tim, awesome that you are doing this. What is your idea here - only host models you use (and have vetted?), or create a general spice lib where people can 'submit' components?

Wow, great collection Tim!

I was thinking the same thing as Newbie, do you intend to create a collection with external contributors, or just sharing yours?
Just the other day I was trying to simulate a crystal filter and the crystal model in ltspice needs lots of parameters that I couldn’t find in the datasheet of my crystal. Do you know how to simulate crystals?

Thanks,
Miti

Just mine, yeah.  Obviously, I want to avoid anything that's copywritten (the MCP6561 may be questionably fair use?) or proprietary (i.e., that I wrote in the course of a project).  Also, publicly available models aren't interesting (you all know how to search manufacturers' websites, right?..).

Suppose I can add links to other sites.  Could host others' files, just put them in a section, with a relevant description (including licensing, presumably something open?).

I want to add detail to a few; it feels like the S/PMETERs deserve an example.  That would be an Altium project demonstrating them: PrjPcb, SchDoc, SchLib and ckt in a ZIP.  I think I want more example material on my site, and little play/test circuits are an easier way to go about that.

Speaking of nonlinear ferrite beads, this looks interesting:

It's still high level though, not like they give SPICE code.

Added an example project and some detail to these models:

Also reviewed the Coilcraft models and improved compatibility.
