Abstract
A PTC device includes a protection component and an electrode connected to the protection component. The electrode includes first and second conductive materials. The first conductive material is adjacent the protection component and the second conductive material such that the first conductive material is sandwiched between the two. The first conductive material and the second conductive material prevent solder from touching the protective component.

A positive temperature coefficient (PTC) device comprising:
- a protection component;
- and
- an electrode coupled to a first side of the protection component, the electrode comprising:
- a first conductive material disposed adjacent the protection component, wherein the first conductive material is a nodular side of a nodular foil;
- a second conductive material disposed adjacent the first conductive material, the first conductive material being sandwiched between the protection component and the second conductive material, the second conductive material being a shiny side of the nodular foil, wherein the first conductive material and the second conductive material prevent solder from touching the protection component.
