ANTI-SURGE OVER-CURRENT PROTECTION DEVICE

摘要

An anti-surge over-current protection device comprises a PTC material layer, first and second conductive layers. The PTC material layer has opposite first and second planar surfaces. The first conductive layer is in physical contact with the first planar surface and comprises a plurality of first conductive members isolated from each other. The second conductive layer is in physical contact with the second planar surface, and comprises a plurality of second conductive members isolated from each other. The first conductive layer, the PTC material layer and the second conductive layer form a circuit containing first and second conductive paths. In the first conductive path, the PTC material layer forms a first series connection resistive component having at least two resistors. In the second conductive path, the PTC material layer forms a second series connection resistive component having at least two resistors.
