Abstract
A solid electrolytic capacitor containing a capacitor element that includes an anode, dielectric layer, and solid electrolyte is provided. The anode is formed from a plurality (e.g., two or more) of separate components, which allows the properties of each component (e.g., density, quality, etc.) to be more readily controlled during manufacturing. The components are electrically connected using a refractory metal paste (e.g., tantalum paste) that sinter bonds to the components to form a strong and reliable connection. The ability to reliably bond together separate components enables the use of a wide degree of possible cross-sectional profiles for each individual component. For example, the components may posses a relatively complex profile that contains one or more indentations and/or projections for increasing surface area. Despite the complex profile, the components may be readily connected to each other in accordance with the present invention to form the anode.
