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