Abstract: An over-current protection device includes first and second electrodes and a multilayered structure including first and second PTC polymer material layers that are stacked one above the other and that are bonded to each other. The first PTC polymer material layer includes a first polymer matrix and a particulate conductive filler. The second PTC polymer material layer includes a second polymer matrix and a particulate conductive filler. The second polymer matrix is made from a second polymer composition that contains. One of the first and second polymer compositions contains polyvinylidene fluoride and polyolefin and the other of the first and second polymer compositions contains polyolefin or polyvinylidene fluoride.
