The Imp: C8 tantalum rating

[benny_profane]

Does this cap need to be 25v (per the build doc)? It's off of the Vb rail (4.5v) and doesn't seem to be exposed to a larger potential.

16v is fine. Most 1uf tantalum caps I've seen though are usually 35 volt.

Thanks, I've got some 16v caps in my stock and was curious. I'm reading the schematic correctly, right? That it's on the 4.5v rail and only has that potential?

C8 is on the 4.5v rail in a roundabout way. 16v will be fine for cap.
