Performance Test:

Test Item	Test Condition	Performance
Temperature coefficient	Test the resistance value at normal temperature added 100℃,calculate per ℃ resistance value rate.	±350ppm/℃
Short time overload	2~4W:According 5 times rated voltage ,5~10W: According 10 times rated power to account the voltage or max .overload voltage (get the lower)for 5 seconds.	ΔR≤±(2%R0+0.05Ω)
Resistance to soldering heat	Immerge into the 350±10℃ tin stove for 2~3 seconds.	ΔR≤±(1%R0+0.05Ω)
Solderability	Immerge into the 245±3℃ tin stove for 2~3 seconds.	The soldering area is over 95%
Temperature cycling	At -55℃ for 30 min,then at +25℃ for 10~15 min,then at +275℃ for 30 min,then at +25℃ for 10~15min, total 5 cycles.	ΔR≤±(1%R0+0.05Ω)
Load life in humidity	Overload rated voltage or Max. working voltage(get the lower)for 1000 hours (1.5 hours on and half-hours off) at the 40±2℃ and 90~95% relative humidity.	ΔR≤±(5%R0+0.05Ω)
Load life in heat	Overload rated voltage or Max. working voltage(get the lower)m for 1000 hours (1.5 hours on and half-hours off) at the 70±2℃.	ΔR≤±(5%R0+0.05Ω)
Nonflammability	Respectively load AC voltage by5,10,16 times rated power for 5 min.	No visible flame
