What is aging a capacitor?

Each capacitor is aged and tested before being packed. The purpose of aging is to repair any damage in the oxide layer and thus reduce the leakage current to a very low level. Aging is carried out at elevated temperature and is accomplished by applying voltage to the device while carefully controlling the supply current.

How is a capacitor assembled?

The winding is assembled to the capacitor Al-can and to the Al-lid. The can is filled with electrolyte and the winding is impregnated during a vacuum treatment. The capacitor is sealed. Throughout the process, all materials inside the housing must be maintained at the highest purity and be compatible with the electrolyte.

How long does it take to make a capacitor?

The process takes between 2 and 20 hours, depending on voltage rating. Damage to the oxide layer can occur due to a variety of reasons: • Slitting of the anode foil after forming • Attaching the tabs to the anode foil • Minor mechanical damage caused during winding The following tests are applied for each individual capacitor.
