Notes:

"s" means mini size ;
Rated voltage V= ;
If the calculated rated voltage is higher than the max working voltage ,it will be got the lower value .

Performance test :

Test item	Test condition	performance
Temperature coefficient	Test the resistance value at normal temperature and normal temperature added 100ºC ,calculate per ºC resistance value change rate	±100ppm/ºC
Short time overload	2.5Xrated voltage or max overload voltage (get the lower) for 5 seconds	R≤±(0.5%Ro+0.05Ω)
Pulse overload	At 4Xrated voltage or max pulse overload voltage (get the lower) cycle 10000±200 times(1 second on ,25 seconds off)	R≤±(1%Ro+0.05Ω)
Resistance to soldering heat	Immerge into 350±10ºC tin stove for 2~3 seconds	R≤±(0.5%Ro+0.05Ω)
solderability	Immerge into 260±5ºC tin stove for 2~3 seconds	The area of soldering is over 95%
Temperature cycling	At -55ºC for 30 minutes ,then at +25ºC for 10~15 minutes,then at +125ºC for 30 minutes ,then at +25ºC for 10~15 minutes,total 5 cycles	R≤±(0.5%Ro+0.05Ω)
Load life in humidity	Overload rated voltage or max working voltage (get the lower) for 1000hours (1.5 hours on and half-hour off) at the 40±2ºC and 90~95% relative humidity	R≤±(2%Ro+0.05Ω)
Load life in heat	Overload rated voltage or max working voltage (get the lower) for 1000 hours (1.5 hours on and half-hour off) at the 70±2ºC	R≤±(2%Ro+0.05Ω)
