IH : Hold current: maximum current device will pass without interruption in 25°C still air.
IT : Trip current: minimum current that will switch the device from low resistance to high resistance in 25°C still air.
VMAX : Maximum continuous voltage device can withstand without damage at rated current.
IMAX : Maximum fault current device can withstand without damage at rated voltage.
Pb : Power dissipated from device when in the tripped state in 25°C still air.
RMIN : Minimum resistance of device as supplied at 25°C unless otherwise specified.
R1MAX : Maximum resistance measured one hour post-trip or post-reflow at 25°C.
* Maximum resistance is measured 1 hour after reflow.
**Ambient operating temperature:-40℃~85℃
Caution：Operation beyond the specified ratings may result in damage and possible arcing and flame.
