About use at high altitudes
Operating and transporting aluminum electrolytic capacitors at altitudes of approximately 12,000 m do not cause problems with the sealing functions.
However, the electrical properties of aluminum electrolytic capacitors are temperature-dependent. Lower temperatures at high altitudes cause decreased capacitance and increased internal resistance (ESR). As such, please confirm device operation at the ambient temperature of the environment in which it will be used.
