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

According 10
times rated power to account the voltage or max .overload voltage (get the lower)
for 5 seconds.

R≤±(2%+0.05Ω)

Resistance to soldering Heat

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

R≤±(1%+0.05Ω)

Solderability

Immerge into the 235±3°C tin stove for 2~3seconds.

The soldering area is over95%

 

Temperature cycling

At -55°C for 30 min. ,then at+25°C for 10~15°C,then at +155°C for 30 min., then at +25°C for 10~15 min., total 5cycles.

 

R≤±(1%+0.05Ω)
