TEST METHOD
Storage Conditions and Control for Aluminum Electrolytic Capacitor
1.Store the capacitor at a temperature of 5℃ to 35℃ and at a relative humidity of less than 75%
2.Store the capacitor in low temperature places free from direct sun shine.
3.Store the capacitor in places free from oil vapor﹑salt water vapor.
4.Store the capacitor in places far from toxic gases ( chlorine﹑ammonium﹑hydrogen sulfide﹑ sulphurous
acid﹑nitric acid , etc ) .
5.Store the capacitor in place free from Ozone﹑ultraviolet ray or radiation .
