When low DC voltage is applied the peak negative ripple voltage cannot exceed 10% of the rated voltage of the capacitor 4. Sudden charge or discharge 4.1. Sudden charge or discharge may result in short circuits or large leakage currents. Protection circuits are needed when the following conditions are present 4.1.1. Inrush current exceeding 10A 4.1.2. Inrush currents exceeding 10 times the ripple current of the capacitor 5. Ripple current 5.1. The applied the ripple current is not to exceed the ripple current rating of the capacitors. Excessive ripple currents may cause the leakage current to increase and short circuits may develop due to self-heating 6. Leakage current 6.1. If the capacitors are exposed to any of the following the leakage current may increase 6.1.1. After soldering or reflow soldering 6.1.2. No load high temperature 6.1.3.
