Performance 

Temperature Coefficient

The resistance value at normal temperature and normal temperature added 100°C, calculate per °C resistance value change rate.

±300ppm/°C

Short Time overload

10×rated voltage or Max. overload voltage(get the lower) for 5 seconds.

 

R≤±(0.5%R0+0.05Ω)

Pulse overload

At 4×rated voltage or Max. pulse overload voltage(get the lower)cycle 10000±200times(1second on,25 seconds off).

 

R≤±(1%R0+0.05Ω)

Resistance to soldering Heat

Immerge into the 350±10°C tin stove for 2~3seconds.

R≤±(0.5%R0+0.05Ω)

Solderability

Immerge into the 245±3°C tin stove for 2~3seconds.

The soldering area is over 95%

 

Temperature cycling

At -55°C for 30 min. ,then at+25°C for 10~15°C,then at +125°C for 30 min., then at +25°C for 10~15 min., total 5cycles.

 

R≤±(0.5%R0+0.05Ω)

 

Load life in humidity

Overload rated voltage or Max. working voltage(get the lower) for 1000 hours(1.5hours on and 0.5 hours off) at the 40±2°C and 90~95% relative humidity.

 

R≤±(2%R0+0.05Ω)

 

Load life in heat 

Overload rated voltage or Max. working voltage(get the lower) for 1000 hours(1.5hours on and 0.5 hours off) at the 70±2°C.
