    Abstract: A solid electrolytic capacitor that comprises a sintered porous anode, a dielectric layer that overlies the anode body, and a solid electrolyte overlying the dielectric layer is provided. The anode is formed from a finely divided powder (e.g., nodular or angular) having a relatively high specific charge. Despite the use of such high specific charge powders, high voltages can be achieved through a combination of features relating to the formation of the anode and solid electrolyte. For example, relatively high press densities and sintering temperatures may be employed to achieve “sinter necks” between adjacent agglomerated particles that are relatively large in size, which render the dielectric layer in the vicinity of the neck less susceptible to failure at high forming voltages.

  • Patent number: 9916935
    Abstract: A solid electrolytic capacitor that contains a capacitor element including an anode body, a dielectric layer, and solid electrolyte is provided. The capacitor element also includes an anode lead (e.g., wire, tape, etc.) that is electrically connected to the anode body. A first portion of the anode lead is embedded within the anode body, while a second portion of the anode lead extends from the anode body in a longitudinal direction. Contrary to conventional capacitors in which the exposed portion of the anode lead is supported by a complex and bulky lead frame assembly, there is no lead frame present in the capacitor of the present disclosure. Thus, the volumetric efficiency of the finished capacitor can be increased. An assembly containing a matrix of multiple solid electrolytic capacitor elements is also provided, as is a method for forming a matrix that comprises multiple solid electrolytic capacitor elements.
