摘要： The present invention discloses an over-current protection apparatus for high voltage, which connects the ceramic current-sensing element and polymer current-sensing element in series to form a novel over-current protection apparatus. By the characteristic of the polymer current-sensing element having higher switching off speed, the invention first responds to the over-current by raising its temperature, and then the heat is thermally conducted through the adhesive layer to the ceramic current-sensing element, resulting in a voltage drop produced by the over-current partially or predominantly received by the ceramic current-sensing element. Thus, the over-current protection device of the invention not only can endure high voltage (>600V), but also will not exhibit a negative temperature coefficient phenomenon.

摘要： The present invention discloses a surface mountable device comprising a current-sensitive element and two electrodes. The current-sensitive element is composed of a PTC conductive composite, comprising at least one polymer and a conductive filler. The feature of the present invention is that the current-sensitive element is a three-dimensional bent structure so that the shape, length and height of the device can be varied according to the space of the circuit board and the resistance of the surface mountable device. Therefore, the mountable surface of the circuit board can be used more efficiently. Moreover, the area of the current-sensitive element of the present invention is larger than that of the conventional surface mountable device. Consequently, the normal resistance of the surface mountable device of the present invention is smaller than that of the conventional surface mountable device and the voltage endurance of the surface mountable device of the present invention is increased.

摘要： The present invention reveals an over-current protection apparatus comprising a first electrode plate, a second electrode plate, a third electrode plate, a conductive element and a high resistance material layer, where the high resistance material layer may contact the first electrode plate to form a conducting path, the conductive element is connected to the first electrode plate and the second electrode, the thermally expanded conductive element can cut off current, the high resistance material layer is connected to the third electrode plate and the second electrode plate, and the thermal expansion coefficient of the high resistance layer is less than that of the conductive element. By virtue of the thermal expansion of the conductive element due to an over-current, the first electrode plate is departed from the third electrode plate so as to enforce the current flows through the high resistance material layer for current reduction. In addition, the heat generated from the high resistance material layer can be transferred to the conductive element to keep the conductive element expanded to cut off current.
