We recommend the following conditions for storage:
a) Do not store capacitors at a high temperature or in high humidity.
Store the capacitors indoors and a temperature of 5～35℃ and a humidity of 70% R.H.
b) Store the capacitors in places free from water, oil or salt water.
c) Store the capacitors in places free from toxic gasses (hydrogen sulfide,sulfurous acid, chlorine, ammonium, etc.)
d) Store the capacitors in places free from ozone, ultraviolet rays or radiation.
e) Keep capacitors in the original package.
f) When the capacitor is stored for a long time without applying voltage,Leakage current tends to increase. This returns to normal by applying the rated voltage to the capacitor before use.
g) It is recommended to apply D.C. working voltage to the capacitor for 30 minutes through 1KΩ of protective series resistor, if it is stored more than 6 months.
