ＰＰＴＣ过电流保护装置;PPTC OVER-CURRENT PROTECTION DEVICE

摘要

一种PPTC过电流保护装置，包含：一第一PPTC组件，具有一第一金属箔层及一第一PTC元件，该第一PTC元件包括一第一聚合物基质，该第一金属箔层是连接于该第一聚合物基质；及一第二PPTC组件，具有一第二金属箔层及一第二PTC元件，该第二PTC元件包括一第二聚合物基质，该第二金属箔层是连接于该第二聚合物基质。该第一及第二PPTC组件是叠加一个于另一个之上且彼此接合。; and a second PPTC component that has a second metal foil layer and a second PTC element including a second polymer matrix. The second metal foil layer is bonded to the second polymer matrix. The first and second PPTC components are stacked one above the other and are bonded to each other.
