The high electric field around the capacitor periphery is effectively relieved in the ELC and thus the breakdown performance is significantly enhanced. 2. Devices structure and experiments
When exposing the capacitors to high temperatures, there appears the shrinking and expansion of the dielectric films, which eventually leads to disconnection due to the different thermal mismatch with the end sprayed metal. This delamination or defects will cause higher impedance and dissipation factors, as described in the next section.
