Storage of Aluminium Electrolytic Capacitors.

We recommend the following conditions for storage :

1. It is recommended to keep capacitors between the ambient temperatures of 5℃ to 35℃ and a relative humidity of 75% or below.
2. Confirm that the environment does not have any of the following conditions :
   1. Damp conditions such as water, saltwater spray, or oil spray or fumes. High humidity or humidity condensation situations.
   2. In an atmosphere filled with toxic gasses (such as hydrogen sulfide, sulfurous acid, nitrous acid, chlorine, ammonia, etc.)
   3. Being exposed to direct sunlight, ozone, ultraviolet ray, or radiation.
   4. Being exposed to acidic or alkaline solutions.
3. Keep capacitors in the original package.
4. Storage life & Re-aging : When Aluminium Electrolytic Capacitors are stored without applied voltage, their L.C.(Leakage Current) characteristic increases over time. For long-term stored products, the following treatments must be performed before use :
   1. For Low Voltage Aluminium Electrolytic Capacitors (i.e., Working Voltage W.V. ≦120V) : After one year of storage, a test must be performed before use.
   2. For Medium/High Voltage Aluminium Electrolytic Capacitors (i.e., Working Voltage W.V. ≧160V) :
      1. If stored for more than 6 months, a test must be performed before use to ensure lifespan and quality.
      2. If stored for 6-24 months and the L.C. value is between 25% and 40% of the specified value, it is recommended to recharge.
   3. Re-aging condition : It is recommended to apply D.C. working voltage to the capacitor for 2 hours.
