How To Know The Polarity Of A Capacitor. The best way is to look at the physical capacitor. The old one has a black screw on one terminal and a gold one on the other though the black screw is where the capacitor appeared to leak so it.
If there is no or - you can orient the capacitor either way. Some capacitors use a colored bar or a ring-shaped depression to show polarity. The polarity of surface mount capacitors is marked by a white or black line at one of the ends of the device.
At about 127 the capacitor shown is BIPOLAR meaning it is NOT polarized.
The old one has a black screw on one terminal and a gold one on the other though the black screw is where the capacitor appeared to leak so it. The value and working voltage is obvious. The polarity is marked by a bar to indicate the negative terminal. If not a notch the IC might have an etched dot in the casing near pin 1.
