Abstract
A PTC device comprises a current and temperature sensing element, a first insulating layer, a second insulating layer, a first electrode layer and a second electrode layer. The current and temperature sensing device is a laminated structure comprising a first conductive layer, a second conductive layer and a PTC material layer. The first and second conductive layers are disposed on first and second surfaces of the PTC material layer, respectively. The second surface is opposite to the first surface. The first and second insulating layers are disposed on the first and second conductive layers, respectively. The first electrode layer is disposed on the first insulating layer and electrically connects to the first conductive layer. The second electrode layer is disposed on the second insulating layer and electrically connects to the second conductive layer. Corners of the current and temperature sensing device are provided with insulating members.
