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 [...]

Military DC High Voltage Ceramic Capacitors

Military DC high voltage ceramic capacitors use DC voltage as the working voltage, which is often more stringent than civilian ones. There will be clear indicators in all aspects, mainly in the following aspects: 1. Tinned layer; 2. Lead or screw lead; 3. Loss angle; 4. Capacity deviation; 5. Temperature shock and voltage treatment (voltage-temperature limit); [...]
