I hold = Hold current: maximum current device will pass without tripping in 20°C still air.
R typ = Typical resistance of device in initial (un-soldered) state.
I trip = Trip current: minimum current at which the device will trip in 20°C still air.
R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow
soldering of 260°C for 20 sec.
V max = Maximum voltage device can withstand without damage at rated current (I max)
Caution: Operation beyond the specified rating may result in damage and possible arcing
and flame.
I max = Maximum fault current device can withstand without damage at rated voltage (Vmax)
P d = Power dissipated from device when in the tripped state at 20°C still air.
R min = Minimum resistance of device in initial (un-soldered) state.
