Hello.
I have done a PCB layout and am putting a order for the components I need, I probably should have picked a SMD size and stuck with that but I have used both 1206 and 0805 since 0805 does save space but 1206 allows to be used as a jumper so I can route a or two signals in between its pads.
I am buying ceramic capacitors and I have two different voltage levels that they are to be used, so I need 0805 0,1µF on a ~40V rail and 0805 0,1µF on a 5V rail.
First of all the prices vary with a almost ridiculous range, for one cap I can choose to pay 0,86kr or 7,38kr and it vary more with other components sometime. 1 USD ~7kr
While the price differ the material in the cap does not both is X7R but I have to think that the more expensive should have less parasitics and such, no?
Back to the 0805 0,1µF caps, I was going to order them all as 50V caps but I'm just taking a easier path.
Am I wrong doing this or not? I mean is there any reason to buy two kinds, I am only buying small quontetyes anyway so bulk price does not come in to it.
There datasheets offer no info at all.
