Solid Electrolytic Capacitor

摘要

A capacitor for use in relatively high voltage environments is provided. The solid electrolyte is formed from a plurality of pre-polymerized particles in the form of a dispersion. In addition, the anode is formed such that it contains at least one longitudinally extending channel is recessed therein. The channel may have a relatively high aspect ratio (length divided by width), such as about 2 or more, in some embodiments about 5 or more, in some embodiments from about 10 to about 200, in some embodiments from about 15 to about 150, in some embodiments from about 20 to about 100, and in some embodiments, from about 30 to about 60.

主权项

1. A solid electrolytic capacitor comprising:
an anode that comprises a sintered porous anode body extending in a longitudinal direction, wherein the anode body contains a sidewall positioned between a proximal end and an opposing distal end, wherein a longitudinally extending channel is recessed into the sidewall; a dielectric overlying the anode body; and a solid electrolyte overlying the dielectric, wherein the solid electrolyte comprises a plurality of pre-polymerized conductive polymer particles.
