That line signifies the lead connected to the outside foil on a non-polar cap, that can be important for sensitive high gain circuits, so that lead should be connected to the lower impedance node in the circuit generally. On a polar cap, like an electrolytic, it indicates the negative lead. Mike. WebJun 20, 2024 · 2024-06-20 12:56 pm. #2. Measure: wrap around some kitchen aluminium foil and measure capacitance between the foil and each ends. Higher measured vaue belongs to the outer foil. Empirically: hold the capacitor in your hand and touch each lead to the input of an audio amplifier. Higher hum belongs to the outer foil.
