I trip = Trip current: minimum current at which the device will trip in 20°C still air. V max = Maximum voltage device can withstand without damage at rated current (I max) 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. R typ = Typical resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 20°C measured one hour after tripping or reflow soldering of 260°C for 20 sec. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. © 2021 Littelfuse, Inc. 1 Specifications are subject to change without notice.
