摘要： A radial-leaded over-current protection device includes a PTC device, first and second electrode leads and an insulating encapsulation layer. The PTC device has first and a second conductive layers and a PTC material layer therebetween. The PTC material layer has a resistivity less than 0.18 Ω-cm and includes crystalline polymer and conductive ceramic filler. The ceramic filler has a resistivity less than 500 Ω-cm and is 35-65% by volume of the PTC material layer. The first electrode lead has an end connecting to the first conductive layer, whereas the second electrode lead has an end connecting to the second conductive layer. The insulating encapsulation layer wraps the PTC device and the ends of the conductive layers. The radial-leaded over-current protection device at 25° C. has a value of hold current thereof divided by an area of the PTC device ranging from 0.027-0.3 A/mm2. Each electrode lead has a cross-sectional area of at least 0.16 mm2.

摘要： An over-current protection device, which can be surface-mounted and stand upright on a circuit board and withstand 60 to 600 volts, comprises a PTC device, first and second electrodes. The PTC device is a laminated structure comprising first and second conductive layers and a PTC material layer. The first and second conductive layers are in physical contact with first and second planar surfaces of the PTC material layer, respectively. The first electrode is disposed on the first conductive layer. The second electrode is disposed on the second conductive layer and is separated from the first electrode. The first electrode, the second electrode and the PTC device commonly form an end surface which is substantially perpendicular to the first and second planar surfaces. The first electrode and the second electrode at the end surface serve as interfaces electrically connecting to the circuit board.
