- | Smaller value capacitors (i.e. usually under 1 uF) generally have no polarity. Anything above 1 uF is typically an electrolytic capacitor, and it will have a polarity marking. Most often the "-" side is marked with a big stripe, although sometimes it's the "+" side that is marked. (Strangely, the "+" side seems to be marked on capacitors made in U.S.A.) | + | **Smaller value capacitors (i.e. usually under 1 uF) generally have no polarity**. **Anything above 1 uF is typically an electrolytic capacitor, and it will have a polarity marking**.
