Kemet has been doing tantalum capacitors for a long time, and hence they're pretty good quality. No big deal at all.
Since you're using Mouser and Digikey, here are some hints for keeping the cost of parts down on one-off projects:
1. Always cross check every part number with both distributors to see who sells it cheaper. For example, Mouser has those Kemet tantalum caps for less than Digikey.
2. Digikey adds a $5.00 handling fee to orders under $25, while Mouser does not.
3. United States Postal Service cost less than UPS Ground for orders of 1lb or less.
4. Small Resistors - Yageo are the cheapest at Digikey with minimum quantities of 5 and Xicon are the cheapest at Mouser with minimum quantities of 10. As of recent I've noticed that all the 1/4 and 1/2 watt carbon film yageos I buy are under value by the same amount, despite the +/- 5% rating, while the xicon metal film are all slightly above by the same amount. If you can analyze the circuit and figure out which resistors do not need to be exactly in tolerance you'll save money by using Yageo carbon film there.[/quote]
Thanks, FH, good to know for the future. As it turns out, I bungled the whole ordering process from stem to stern. I ordered an all aluminum chassis from par-metal, then noticed that the SSL parts list that folks put together indicated the the aluminum and steel ones are fine (and $50 less!), my mouser order got submitted twice and hence was twice as expensive, etc. got it all sorted out now. And I thought building it would be the tough part!
