1. A solid electrolytic capacitor comprising:
a capacitor element that contains a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric;
an anode lead extending from a surface of the capacitor element;
an anode termination that is in electrical connection with the anode lead and a cathode termination that is in electrical connection with the solid electrolyte,
a casing material that encapsulates the capacitor element and anode lead; and
a barrier coating that is disposed on at least a portion of the capacitor element and is in contact with the casing material, wherein the coating comprises a polymeric material that includes a fluorinated component and a non-fluorinated component, wherein the polymeric material has a glass transition temperature of from about 10° C. to about 120° C. and a thermal decomposition temperature of about 200° C. to about 300° C., and wherein the non-fluorinated component includes a (meth)acrylate.
