IT = Trip current: minimum current at which the device will always trip at 25℃ still air reflow soldering of 260℃ for 20 sec. Vmax = Maximum continuous voltage device can withstand without damage at rated current Imax = Maximum fault current device can withstand without damage at rated voltage. Ttrip = Maximum time to trip(s) at assigned current reflow soldering of 260℃ for 20 sec. Pdtyp = Typical power dissipation: typical amount of power dissipated by the device when in state air environment. (Sec.) Pd typ (W) Rmin (Ω) R1max (Ω) 0.10 0.6 0.15 0.80 Rmin = Minimum resistance of device in initial (un-soldered) state. R1max = Maximum resistance of device at 25℃ measured one hour after reflow soldering of 260℃ for 20 sec. Value specified is determined by using the PWB with 0.030＂*1.5oz copper traces. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.
