Items with S and SS at end of part number identify items with slit lead option. 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 (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 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 re?ow
soldering of 260°C for 20 sec.
Caution: Operation beyond the speci?ed rating may result in damage and possible arcing
and ?ame.
