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.
