Notes:  
IH  
: Hold current: maximum current device will pass without interruption in 25°C,  
unless otherwise specified.  
: Trip current: minimum current that will switch the device from low-resistance to  
high-resistance in 25°C still air, unless otherwise specified.  
RMIN : Minimum resistance of device as supplied at 25°C, unless otherwise specified.  
R1MAX: Maximum resistance of device when measured one hour post trip at 25°C unless  
otherwise specified.  
RaMAX : Maximum functional resistance of device after being subjected to the stresses  
described in AEC-Q200 at 25°C, unless otherwise specified.  
IT  
VMAX : Maximum voltage device can withstand without damage at rated current.  
IMAX : Maximum fault current device can withstand without damage at rated voltage.  
PD : Power dissipated from device when in the tripped state in 25°C still air,  
unless otherwise specified.
