For anyone who's interested, I went to the Würth Elektronik site and located pages for all of the component kits included design challenge kit. Lots of really great components. And from what I can tell most or all of the kits come with a lifetime refill policy. Thanks to Würth Elektronik for a great component package!
Just to get a little jump start on knowing what we have to work with. See the links below.
These are the three capacitor kits.
