Hello - I'm trying to complete this circuit and am having a hard time sourcing the right capacitor. It needs to be a .1uF
At first I got a ceramic capacitor, but then read you should not use ceramic ones for analog circuits. So then I got a few of these. The bin said they were .1 mfd (I assume that meant micro farad which = .1uF?) But looking at the top it seems to say either ".1K100" OR "1K100" and the dot indicates the polarity (+)? Or do I need to run to radioshack and get a cap that is more barrel shaped that has obvious polarity (electrolytic I believe they are called)
Thanks!
