Abstract: A solid electrolytic capacitor comprising a capacitor element, anode lead extending from a surface of the capacitor element, an anode termination that is in electrical connection with the anode lead, a cathode termination that is in electrical connection with the solid electrolyte, and a casing material that encapsulates the capacitor element and anode lead is provided. An interfacial coating is disposed on at least a portion of the anode termination and/or cathode termination and is in contact with the casing material. The coating contains a hydrophobic resinous material and the adhesion strength of the casing material is about 5 newtons per square millimeter or more as determined at a temperature of about 23° C. and relative humidity of about 30%.
