Introduction

I_H: Hold Current — the maximum current at which the device will not trip in still air at 25°C. I_F: Trip Current — the minimum current at which the device will trip in still air at 25°C. V_max: Maximum Voltage — the maximum voltage the device can withstand at rated current without damage. I_max: Maximum Fault Current — the maximum fault current the device can withstand at rated voltage without damage. T_trip: Maximum Time to Trip — the maximum time to trip at the specified current (seconds). Pd_typ: Rated Power Dissipation. R_min: Minimum Resistance — the minimum resistance of the device prior to tripping at 25°C. Rl_max: Maximum Resistance — the maximum resistance of the device measured at 25°C one hour after reflow soldering. Note: All electrical functional tests are performed after PCB mounting.
