Deleted member 115935 Joined Dec 31, 1969 0 Nov 24, 2020 #13 just look on the sites such as digikey , the biggest 0402, 25V X7R I can see is 220 nf
MrChips Joined Oct 2, 2009 26,060 Nov 24, 2020 #14 Here are your constraints: 1 - value = 1μF 2 - voltage = 25V 3 - temperature range = X7R 4 - package = 0402 5 - PCB layout Change any one of those and you have a fit. Edit: Before someone jumps on me, I know, changing 4 and 5 are two changes.
