Hi there, well i've mostly built up a couple of buffers to using in a dac mod for a friend; all except the caps for C6 and C7. I have some Nichicon KZ 100uf 25v and elna silmic II in 100uf and 220uf 25v through-hole caps on the way, but since I have quite a few of these boards and wanted to play around with different combinations, I wondered how vital the capacitance is in these positions. I would expect that since these are supply/reservoir caps, that the value is more flexible than other parts on the board. I have some caps that I have found nice in digital circuits sanyo SVP, the SMD version; in 82uf and 330uf. I would lean towards over specing with the 330uf, rather than underspeccing, but wondered what your opinion was?? main thing I see is these are only rated really for digital circuits, so are 16v. I will be supplying these with only +/- 10v in this build, so should be fine right?? the nichicons are 25v and 50v and the silmic II 25v. I have enjoyed these sanyos in low voltage supplies before as well and as they are SMD, they are nice and neat/compact; very suitable for the space these are going into.
any opinions welcomed, mostly i'm just checking im on the right track, power supply reservoirs I prefer to go large, but if I can get away with the 82uf, that would be swell as they are smaller
thanks in advance
