I hold = Hold current: maximum current device will pass without tripping in 20°C still air. I trip = Trip current: minimum current at which the device will trip in 20°C still air. R min = Minimum resistance of device in initial (un-soldered) state. V max = Maximum voltage device can withstand without damage at rated current (I max) R typ = Typical resistance of device in initial (un-soldered) state. I max = Maximum fault current device can withstand without damage at rated voltage (Vmax) R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec.
