> Another big one is having multiple capacitors one decade apart for decoupling, ie 1uF, 0.1uF and 10nF or something like that. With modern SMD capacitors you'll almost never want to do that. Instead use multiple large ones, ideally in the smallest package you can. To expand (search for "antiresonance"): https://www.mouser.com/pdfDocs/c39e.pdf https://www.mouser.com/pdfDocs/c39e.pdf
