**Ih** = Hold current-maximum current at which the device will not trip at 23°C still air.
**It** = Trip current-minimum current at which the device will always trip at 23°C still air.
**Vmax** = Maximum voltage device can withstand without damage at it rated current.(Imax.)
**Imax** = Maximum fault current device can withstand without damage at rated voltage. (Vmax.)
**Pd** = Typical power dissipated-type amount of power dissipated by the device when in the tripped state in 23°C still air environment.
**Rmin** = Minimum device resistance at 23°C prior to tripping.
**R1max** = Maximum device resistance at 23°C measured 1 hour after tripping or reflow soldering of 260°C for 20 seconds. Termination pad materials: Pure Tin
