Abstract
A capacitor assembly that includes an electrolytic capacitor that contains an anode body, dielectric overlying the anode, and a solid electrolyte overlying the dielectric is provided. An anode lead is also electrically connected to the anode body and extends in a longitudinal direction therefrom. The anode lead is connected to an 'upstanding' portion of a leadframe. Among other things, this helps to limit substantial horizontal movement of the lead and thereby improve the mechanical robustness of the part. The capacitor and leadframe are enclosed and hermetically sealed within a ceramic housing in the presence of an inert gas. It is believed that the ceramic housing is capable of limiting the amount of oxygen and moisture supplied to the conductive polymer of the capacitor. In this manner, the solid electrolyte (e.g., conductive polymer) is less likely to undergo a reaction in high temperature environments, thus increasing the thermal stability of the capacitor assembly.
