<p>A capacitor assembly comprises: a solid electrolytic capacitor element further comprising an anode formed of a sintered, anodised porous body and a solid electrolyte; a housing 222 defining a hermetically sealed interior cavity containing the solid electrolytic capacitor; and cathode 129 and anode 127 terminations which are electrically connected with the cathode and anode, respectively, the terminations 129,127 being located adjacent to the surface of the housing 222 wherein at least one of the cathode 129 and anode 127 termination also contain a section which extends outwardly from the housing in a traverse direction 129b,127b. The capacitor assembly is thermally and mechanically stable under extreme conditions, where the thermal stability is provided by enclosing and hermetically sealing the capacitor element within a housing in the presence of a gaseous atmosphere that contains an inert gas, thereby limiting the amount of oxygen and moisture supplied to the solid electrolyte of the capacitor. The good mechanical stability is obtained as the assembly contains at least one external termination (e.g., anode and/or cathode termination) extending beyond an outer periphery of a surface of the housing. The degree to which the external termination extends beyond the outer periphery relative to the dimension of the housing is selectively controlled to increase the surface area available for soldering to a circuit board.</p> |
