Got it posted in the links below.
Posted here as an addition to the Electrical Materials And Manuals Thread
And as a new thread in the Electrical Forum: PTC and TVS - Some Commonly Used Sizes and Part Numbers
We can use the last link above (the new thread) or this thread for further additions, comments, corrections, discussion, etc. and I will update the post and thread. So we don't clutter up the other 'Reference Materials' thread that's supposed to be just reference materials.
Please let me know if I goofed anything up in the new posts linked above. I think I finally got it all straight, but I originally got a couple of links crossed and like to never got them straightened out again. Seemed like every time I fixed one I goofed up something else...hopefully all fixed now.
