A vacuum capacitor is an electrical part having a low ESR (equivalent series resistance) and an extremely small dielectric loss among many existing capacitors. As such, the allowable current of the capacitor is large at high frequency of 1 MHz to a few 100 MHz, and the capacitor has a very good temperature characteristic.

Thermal-vacuum test screening was performed on three different types of cells, all of which displayed adequate performance following exposure to temperature cycling in a vacuum environment. Based on evaluation of cell masses before and after testing, visual inspection and electrical performance testing, all cell types displayed performance
programs, a thermal vacuum cycle test was performed. The results, as expected, show no impact on the electrical characteristics of the capacitors. The breakdown voltage of polymer capacitors has been evaluated using a steady step surge test. Initial results show the uniform distribution in the breakdown voltage for polymer aluminum capacitors.
