1. A capacitor comprising:
an anode;
an anode wire extending from said anode;
a dielectric on said anode; and
a conductive polymer on said dielectric;
wherein said anode comprises at least one face and at least one perturbation wherein said face comprises a surface area wherein at least 60% of said surface area is a land and no more than 40% of said surface area comprises perturbations and wherein at least one said perturbation of said perturbations is at an angle of more than 90° but less than 140° relative to a vector along a long axis of said anode wire.
