How does the Environment Affect Capacitor Performance?
Capacitors are used in high-altitude environments. As the height increases, the air pressure decreases, and the air resistance decreases. The capacitor will produce arcing and corona phenomena, and the withstand voltage strength of the capacitor will decrease. In addition, in the case of thin air, it is difficult to dissipate heat.
