Long life is important in order to create devices that are maintenance free and have extended warranties. Nichicon’s UPW series offers up to 8000 hours life at 105°C with full ripple current and voltage applied. If a capacitor is not operated at the full rated ripple current and temperature, its life will increase dramatically. As a general rule, for every 10°C drop in ambient temperature, the life of an aluminum electrolytic capacitor is estimated to double.
