摘要：A high voltage over-current protection device includes a positive temperaturecoefficient (PTC) electrically conductive heat-dissipation layer and two metal electrodes.

The PTC electrically conductive heat-dissipation layer includes at least one polymer, anelectrically conductive filler, and a heat conductive filler. Due to the high thermal

conductivity of the heat conductive filler (with a coefficient of thermal conductivity higherthan 1 W/mK), the high voltage over-current protection device has a high thermalconduction characteristic, and the withstand voltage thereof can be substantiallyuniformly distributed in the PTC electrically conductive heat-dissipation layer to enhanceits high voltage withstanding characteristic.
