Solid Electrolytic Capacitor with Integrated Fuse Assembly

摘要

A solid electrolytic capacitor with an integrated fuse assembly is provided. The fuse can be secured in a recess formed in a face of the porous anode body of the capacitor. When the fuse is secured in the recess, the fuse can be substantially flush with the face of the porous anode body in which the recess is formed. Further, the equivalent series resistance (ESR) of the fuse is reduced because the length of the connection between the fuse and the porous anode body is reduced. Further, because the fuse is integrated into the porous anode body, the capacitor can be assembled onto a circuit board via standard pick and place equipment.

1. A solid tantalum capacitor comprising:
a capacitor body having a tantalum wire lead and a recess; a fuse assembly that includes a fuse with two terminations and an adhesive material for securing the fuse in the recess; a connection assembly that includes an electrically conductive material that connects the fuse terminations to the capacitor body; a plating that coats the terminations and conductive material; and a conformal coating that encases at least the capacitor body.
