    Manufacturers of aluminum electrolytic capacitors in storage recommend energizing these components once every 1 or 2 years and the temperature range is 5-35C and humidity is below 75C. After this interval, under these maximum conditions, they recommend refurbishing.



    Do these recommendations only work on new aluminum electrolytic capacitors with little or no use because their chemistry is new and unchanged, or does this recommendation also work on old aluminum electrolytic capacitors that are used and assembled in electronic circuits and manufactured in the early 1990s?

    By far the best way to renew is through replacement.

    Electrolytic capacitor manufacturers say that if you energize them before 2 years of storage (5-35C minus 75% RH) there is no need to refurbish the capacitor.

    Is this only valid for new aluminum electrolytic capacitors with little or also for old capacitors from the 90s and mounted on an electronic circuit that operates at 220V?

    In electronic devices and connected to 220V, how many minutes are necessary to restore the entire dielectric oxide layer (it degrades in storage)?
