Max. working voltage
Max. overload voltage
Max. Pulse voltage
Max. insulation voltage
Rated Power Derating Curve:
Test the resistance value at normal temperature and normal temperature added 100℃,calculate per℃ resistance value change rate .
Short time overload
2.5 × rated voltage or Max.overload voltage (get the lower) for 5 seconds.
At 4 × rated voltage or Max. pulse overload voltage (get the lower) cycle 10000±200 times(1 second on, 25 seconds off ).
Resistance to soldering heat
Immerge into 350±10℃ tin stove for 2~3 seconds.
Immerge into 245±3℃ tin stove for 2~3 seconds.
The area of soldering is over 95%
At -55℃ for 30 min, then at +25℃ for 10~15 min, then at +125℃ for 30 min, then at +25℃ for 10~15 min, total 5 cycles.
Load life in humidity
Overload rated voltage or Max.working voltage (get the lower) for 1000 hours (1.5 hours on and half-hour off ) at the 40±2℃ and 90~95% relative humidity.
Load life in heat
Overload rated voltage or Max.working voltage (get the lower ) for 1000 hours (1.5 hours on and half-hour off) at the 70±2℃.
