Abstract: An electrical component which includes a circuit element such as a solid electrolytic capacitor arranged within a metallic casing or can. One electrical lead of the component is connected to the casing; the other lead is connected to the circuit element and extends through an opening in the casing. This opening is filled with a first plastic material to seal the circuit element within the casing against environmental conditions. A conformable coating of a second plastic material is disposed over the outer surface of the casing and extends over the edges of the casing into the opening so as to join with the first plastic material disposed in the opening.
