    A traditional fuse will break open, and does not recover after the fault event is corrected. The fuse component has to be replaced for the circuit to function again. A PTC fuse is a special fuse that will reset after power is removed from the circuit. It is a temperature-dependent resistor or thermistor whose resistance rises with increasing temperature. A PTC fuse quickly increases its resistance as a response to an overcurrent, over-temperature, or short circuit situation, to restrict the current flow. PTCs enable the equipment to function, with extreme cases being the exception. Circuit designers select PTCs on occasions where maintaining user transparency or constant system uptime is at a premium.

    Quicker trip: A PTC has lower thermal mass and heats up faster. It thus quickly trips into a high-resistance state.

    Smaller size: PTC products occupy a smaller board area and are easier to integrate into package design.

    Low initial resistance: PTCs make a more efficient transformer with their lower resistance.

    No cycling: PTC devices remain in tripped state under fault conditions. PTCs have no arcing if there is a fault situation.

    Ihold = Hold Current. Maximum current device will not trip in 25°C still air.

    Itrip = Trip Current. Minimum current at which the device will always trip in 25°C still air.

    Vmax = Maximum operating voltage device can withstand without damage at rated current (Imax).

    Imax = Maximum fault current device can withstand without damage at rated voltage (Vmax).

    Pd = Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage.

    Rimin/max = Minimum/Maximum device resistance prior to tripping at 25°C.

    R1max = Maximum device resistance is measured one hour post reflow.

    CAUTION : Operation beyond the specified ratings may result in damage and possible arcing and flame.
