FAQ
Is it safe to use aluminum electrolytic capacitors in high altitude?
When aluminum electrolytic capacitors are used in equipment that will be used at high altitudes, such as in the mountains or in airplanes, it is assumed that the pressure inside the capacitor will increase due to a decrease in external air pressure. However, there is no problem in the sealing performance of the capacitor when used in the atmosphere at an altitude of about 10,000m. However, as the temperature drops as the altitude increases, please take into account the temperature dependency of the characteristics of aluminum electrolytic capacitors when checking the operation of the equipment.
