  • Multi-layer over-current protector
    Patent number: 7102483
    Abstract: An over-current protector comprised of multiple over-current protection devices each at various switching temperature and provided with positive temperature coefficient; all devices being stacked and segregated with an reinforced insulation layer and connected in parallel through a conducting mechanism each respectively provided at where in relation to both ends of the device; both conducting mechanisms constituting the terminal electrodes of the over-current protector as a whole for reducing initial resistance, increasing peak resistance, and in turn upgrading voltage withstanding performance.
    Type: Grant
