Aluminum electrolytic capacitors are the most common and polarized capacitors. Let’s discuss what affects the leakage current of aluminum electrolytic capacitors. 1.1 Leakage current and its characterization parameters When a constant DC voltage is applied across the capacitor, its charging current starts to be very large and gradually decreases over time. However, the decline will not [...]
