ABSTRACT:
A film capacitor having moisture resistance includes a capacitor element having (a) a multilayer structure made of stacked dielectric films or a wound dielectric film, each dielectric film having a metallic layer formed on its surface, and (b) a pair of outer electrodes electrically connected to the metallic layer, and a coating layer covering the capacitor element. The coating layer is made from at least one polysiloxane, at least one organometallic compound or a combination of the polysiloxane and the organometallic compound, wherein the organometallic compound is selected from the group consisting of organoaluminum compounds, organosilicon,compounds, organotin compounds and organotitanium compounds. The organometallic compound has at least one functional group attached to the metallic atom of the organometallic compound, the functional group of which is reactive to inorganic and organic materials and represented by the formula -OR, wherein R is selected from the group consisting of hydrogen, hydrocarbyl, oxygen-containing hydrocarbyl, nitrogen-containing hydrocarbyl and oxygen- and nitrogen-containing hydrocarbyl.
