Abstract
A surface-mountable over-current protection device comprises a PTC material layer, first and second conductive layers, first and second electrodes, first and second electrically conductive connecting members. The PTC material layer has a resistivity less than 0.18 Ω-cm. The conductive layers are in contact with opposite surfaces of the PTC material layer. The first electrode comprises pair of first metal foils and is insulated from the second conductive layer. The second electrode comprises a pair of second metal foils and is insulated from the first conductive layer. The first electrically conductive connecting member connects to the first metal foils and conductive layer. The second electrically conductive connecting member connects to the second metal foils and conductive layer. The first electrically conductive connecting member comprises 40%-100% by area of the first lateral surface, and the second electrically conductive connecting member comprises 40%-100% by area of the second lateral surface.
