About use at high altitudes
Use (operating) and transport (not operating) in the atmospheric pressure environments seen at altitudes near 12,000m do not cause problems with the sealing functions of aluminum electrolytic capacitors.
However, the electrical properties of aluminum electrolytic capacitors are temperature-dependent. The temperature declines experienced in high-altitude environments cause a decline in capacitance and increased internal resistance (ESR). As such, we request that you confirm device operation for the temperature of the environment in which it will be used.
