SURFACE MOUNT CHIP CAPACITOR

摘要

A surface mount chip capacitor includes a metal substrate, a conductive powder element comprising a valve metal and partially surrounding the metal substrate with the metal substrate extending outwardly from the conductive powder towards the anode end of the surface mount chip capacitor, a silver body cathode at least partially surrounding the conductive powder element, a coating formed by vapor-phase deposition surrounding the silver body cathode, an insulative material formed about a portion of the substrate extending outwardly from the conductive powder, a conductive coating formed around the metal substrate at the anode end of the surface mount chip capacitor, an end termination anode electrically connected to the conductive coating at the anode end of the surface mount chip capacitor, and an end termination cathode electrically connected to the silver body cathode at the cathode end of the surface mount chip capacitor. The coating preferably comprises a parylene or a parylene derivative.
