What affects the leakage current of aluminum electrolytic capacitors

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 [...]
