Funny how we assume what is inside

Finally got a look under the black and clear covers of the PTC strip. It turns out it is really 6 discrete PTC devices that are connected by stainless steel strips, so the active temperature sensitive area is located right in the center of the cells.Very interesting, I will run a resistance to temperature profile on one, and see what the actual characteristics are.
