FAQ
Is it safe to use aluminum electrolytic capacitors that have been stored for a long time?
When aluminum electrolytic capacitors are stored for a long period of time, the oxidation of the lead wire surface may affect the solderability and the increase in leakage current may cause circuit malfunction. In addition, the characteristics will deteriorate even if the capacitor is not in use.
Even if the product has been stored for a long period of time, the leakage current can be reduced to the initial level by implementing voltage treatment, so it is possible to prevent malfunctions due to the effects of leakage current. However, other characteristics that have deteriorated during the storage period will not return to their original state, so consider the expected lifetime of the set, storage period, and storage conditions when using long-term stored products. For precautions on storage conditions, please refer to the Precautions for Use.
