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)? |

This mainly applies to newer aluminum electrolytic capacitors. For old ones from the '90s, restoring the dielectric layer typically takes a few to several minutes, depending on aging. |

bypass and coupling capacitors can need as much as 24 hours to restoring dieletric layer? |
