The pcb manufacturer must install the capacitor in the correct way or risk damaging both the part and the circuit. Electrolytic capacitors are often marked with a stripe. Supercapacitor Wikipedia Electrolytic Capacitor Wikipedia File Trimmer Capacitor Symbol Gost Svg Wikimedia Commons Capacitor polarity capacitor labeling. Capacitor schematic polarity . For axial leaded capacitors in which the leads come out of the opposite ends of the capacitor there may be an arrow that points to the negative end symbolizing the flow of charge. As shown on the electrolytic cap immediately to the right of the removed part location the thickened part of the outline is where the negative lead of the cap goes. The electrolytic capacitors have polarity. You can also identify the polarity using the negative strip on the capacitor label. On an electrolytic capacito...
