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： A PCB comprising a substrate, at least one circuit layer and at least one insulating layer, characterized in that the PCB further comprises at least one embedded functional material such as a PTC, and NTC and ZTC material. If the PTC material is applied in the present invention, a normal resistance of the present invention will be substantially smaller than that of the conventional PTC protection apparatus since the area of the PTC material of the present invention is larger than that of the conventional PTC protection apparatus. Moreover, through an electrically conductive hole, an upper electrode and a lower electrode respectively lying on top and bottom surfaces of the functional material are respectively connected with an apparatus mounted on a surface of the PCB to form a conductive circuit. Thus, at least one over-current protection apparatus which is usually mounted on the surface of the PCB is eliminated, and the surface utilization rate of the PCB is improved.
