Resistors are so dirt cheap nowadays it's not generally cost effective to make 1% resistors by selecting from a process which makes 5% ones. It's much cheaper to just tune the process so you always get 1% without needing to do the selection. And when you get to higher precisions you have a trimmable design where you adjust the resistance with a laser to get it in spec. |
