I trip = Trip current: minimum current at which the device will trip in 23°C still air. Vint = Maximum voltage the device can withstand without damage at rated current (I max) Vop= The device regular operation voltage 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 23°C still air. R min = Minimum resistance of device in initial (un-soldered) state. R max = Maximum resistance of device in initial (un-soldered) state. R 1max = Maximum resistance of device at 20°C measured one hour after tripping. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. ©2009 Littelfuse, Inc. Specifications are subject to change without notice.
