Abstract
An over-current protection device comprises a PTC material layer, a first electrode layer and a second electrode layer. The PTC material layer has opposite first and second surfaces and opposite first and second lateral surfaces. The first electrode layer is in physical contact with the first surface of the PTC material layer and extends to the first lateral surface. The second electrode layer is in physical contact with the first surface of the PTC material layer and extends to the second lateral surface. The second electrode layer is insulated from the first electrode layer by a first separation. The first electrode layer and the second electrode layer are substantially laterally symmetrical, and serve as interfaces for current flowing in and out of the device when the over-current protection device is in use.
