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 (V max) 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 1max= Maximum resistance of device at 20°C measured one hour after tripping for 20 sec. Caution: Operation beyond the specified rating may result in damage and possible arcing and flame.

The smaller thermal mass of these devices also provide benefit of faster trip time and increase the battery safety level. The LRD devices are ideally suited for battery packs used for portble computer and camcorder applications.
