摘要： An axial leaded over-current protection device comprised of a plurality of PTC devices, a first terminal metal strip, and a second terminal metal strip. One end of the first terminal metal strip diverges into a plurality of electrode strips, and the plurality electrode strips are connected to an electrode layer of each PTC device. The second terminal metal strip is connected to the other electrode layer of each PTC device, i.e., the one not being connected to the first terminal metal strip. Accordingly, the first terminal metal strip and second terminal metal strip are respectively connected to the two electrode layers of each PTC device and become in parallel thereby, so that the resistance of the over-current protection device can be decreased.
