| Dec 6, 2019 at 14:49 | comment | added | GB - AE7OO | @TomCarpenter Why would you require X5R to be x4 compared to the X7R at x2? I've found that as long as I avoid the cheap specials and stick with a decent brand(Kemet, TDK and AVX come to mind) that they both act the same as far as bias goes at room temp(35C +/-5). Even cooler temps are Ok, it's when it gets hotter(lets say over 80C) that if seems to make a difference. But then again I rarely use 401's(except I got a good deal on 15uF 6V X5R 401(500 for $5) which I use for 3V3 decoupling) | |

| Aug 6, 2018 at 11:22 | comment | added | asdfex | You could mention that you don't need ">2x the required DC voltage" - you can just take the decreased capacity into account and take 30% higher nominal capacity. And in decoupling caps absolute values don't matter a lot. | |

| Aug 5, 2018 at 19:41 | comment | added | HeliTux | Thanks for very complex answer. Its now very clear to me how to use MLCCs. I always prefer biggest SMD parts as possilble (never have problems with PCB space), so it seems that MLCC doesnt have any downsides for me. | |
