#1 The current is guaranteed 3.0A in case of the current is turned on/off in a duty-ratio of less than 1/10 with a maximum
on-time of 5ms and when short brake.
#2 PCB (70mm×70mm×1.6mm,occupied copper foil is less than 3%,glass epoxy standard board) mounting.
Reduce power by 11.0mW for each degree above 25℃.
○Recommended operating conditions(Ta=-30～+85℃)
