content: Added:https://www.seventransistorlabs.com/Modeling/SPICE/HI0603P600R_NL.cktwith comparison plot:https://www.seventransistorlabs.com/Modeling/Images/HI0603P600R_Overlay.jpgCorrected 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

content: 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?

content: 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

content: 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.Tim

content: Speaking of nonlinear ferrite beads, this looks interesting:https://www.researchgate.net/publication/224597964_Measurement-Based_Equivalent_Circuit_Model_for_Ferrite_BeadsIt's still high level though, not like they give SPICE code.Tim

content: Added an example project and some detail to these models:https://www.seventransistorlabs.com/Modeling/PMETER.htmlAlso reviewed the Coilcraft models and improved compatibility.Tim
