farwest1 Member Jun 13, 2020 #1 I'm building a circuit that calls for 1uF film caps. The circuit is marked with +/- polarity, but I thought film caps don't have polarity. Is that true? Thanks! Last edited: Jun 14, 2020

Robert Reverse Engineer Jun 13, 2020 #4 Gotcha. If it's anything like the Muffin PCB then it has been designed to accommodate film or electrolytic caps. If you're installing film you can just ignore the polarity markings. Upvote 0 Downvote
