Performance

Temperature coefficient

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

250ppm/°C

Short time overload

2.5 x rated voltage or max. overload voltage(get the lower) for 5 seconds.

ΔR≤±(0.5%R0+0.05Ω)

Resistance to soldering heat

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

ΔR≤±(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 30min,then at +25°C for 10-15min,then at +125°C for 30min,then at +25°C for 10-15min,total 5cycles.

ΔR≤±(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 half-hour off)at the 40±2°C and 90~95% relative humidity.

ΔR≤ ±(3% 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.

ΔR≤ ±(3% R0+0.05Ω)

Pin strength

Solder the lead wire on the Array Resistors Pin , pull strength need reach 500g.

ΔR≤ ±(1% R0+0.05Ω)

No mechanical damage.
