AI Customer ServiceThe storage conditions of electrolytic capacitors are defined in the data sheet. These conditions are temperature between 5 °C and 35 °C with a humidity between 10% and 75%. The quality of the oxide layer can deteriorate during storage without externally applied voltage, especially at higher temperatures.
The shelf life depends on storage conditions. Temperature, atmospheric pressure and humidity. Electrolytic capacitors are most susceptible to high temperatures. The current aluminum electrolytic capacitors shelf life is approximately 2 years. If storing these capacitors at a high temperature rating, it can degrade the sealing material.
There is also a guideline from the ZVEI on the long-term storage capability of components: During storage of an aluminum electrolytic capacitor, two different effects can adversely affect the blocking (insulation) capability of the capacitor, oxide degeneration and post-impregnation effects.
This type of capacitor has an operating temperature of up to 150 °C in some cases, allowing a wide range of operating temperatures. Moreover, compared to other electrolytic capacitors, they are less expensive not only because of the materials used but also because of the manufacturing process. They offer good stability and a long service life.
Also when capacitors have been stored under humid conditions for a long period of time, humidity will cause terminals to oxidize. Therefore it is highly recommended they should be stored at room temperature, in a dry place, out of direct sunlight. A voltage treatment process should be applied after some years storage period.
It is also important to note that other factors that should be avoided when stored. Radiation, oil, ultraviolet rays, and ozone. When storing electrolytic capacitors, it would be a good practice to log when the storage of these devices has started. Here is another post with some general shelf life information.
