ABSTRACT:
An electric device includes an electric element, such as a wound film capacitor, with power input and output leads. The electric element includes a coating layer of parylene that provides moisture resistance and low gas and moisture permeability to protect the electric element from short and long term moisture degradation effects. A known case layer is located adjacent to the coating layer. The case layer is a metal, epoxy-based, silicone-based, or polymer material that encapsulates the coating layer and the electric element to protect the coating layer and electric element from physical damage.
