How is rated voltage applied to a capacitor?

For this purpose, the rated voltage is applied to the capacitors via a series resistance of approxi-mately 100 for VR 100 V DC, or 1000 for VR >100 V DC, for a period of one hour. Subsequently, the capacitors are stored under no-voltage conditions for 12 to 48 hours at a tem-perature between 15 and 35 °C.
