See Dimension Drawing and Part Ordering Number System sections of this document for more information. 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. 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 soldering of 260°C for 20 sec. Caution Operation beyond the rating may result in damage and possible arcing and ST Series 2010 Littelfuse, Inc are subject to change without notice. Please refer to for current information.
