I trip = Trip current: minimum current at which the device will trip in 20C 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 (V max ) P d = Power dissipated from device when in the tripped state at 20C 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 20C measured one hour after tripping or reflow soldering of 260C for 20 sec. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame. 1 Some older references to these devices may include " -C " in the Part Number. The " -C " should be omitted when placing new orders for the device. 2 Part Number with note 2 tested and complied with AEC Q200.
