Performance

 

Temperature Coefficient

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

 

±350ppm/°C

Short Time overload

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

 

R≤±(2%R0+0.05Ω)

Resistance to soldering Heat

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

R≤±(1% 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.在-55°C

 

R≤±(1% 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≤±(5% 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.

 

R≤±(5% R0+0.05Ω)

Nonflammability

Respectively load AC voltage by5,10,16times rated power for 5 minutes. 

No visible flame

Note: We can accord to customer’s requirements to customize the specification and dimension, and produce multiple resistance value of one ceramic tube or cancel the fixed plank.
