Interesting Tutorial on how your 4.7uF Capacitor can become a 0.33uF Capacitor

I just read an incredible article by Mark Fortunato of Maxim Integrated.

For any of you hardware engineers or applications engineers out there, this is a very useful and interesting read about how your 4.7uF capacitor can behave like a 0.33uF capacitor at +85C, which of course is exactly what you don't want to do.
