PakHeng is a professional manufacturer Of forelgn-owned enterprise，has twofactories in China，With 20，000 square meters workshop area，engaged in the resistance design，manufactuing and marketing．We can produce all series resistors，such as Chip Resistors，Chip Array Resistors，Array Resistors，Carbon Film Resistors，Metal Film Resistors，Metal Oxide Film Resistors，Fuse Resistors，MetaI Glaze Resistors，Wirewound Resistors.
1、 Lower resistance value,the least can be meet 0.005Ω.
2、 Operating ambient temperature: -55℃~+155℃
3、 Can be according to customers requirement toforming the special type.
4、 Resistance tolerance:±1%、±5%、±10%。
Test the resistance value at normal temperature and normal temperature added 100℃,calculate per℃ resistance value change rate .
Resistance to soldering heat
Immerge into 350±10℃ tin stove for 2~3 seconds.
Immerge into 245±3℃ tin stove for 2~3 seconds.
The area of soldering is over 95%
At -55℃ for 30 min, then at +25℃ for 10~15 min, then at +125℃ for 30 min, then at +25℃ for 10~15 min, total 5 cycles.
Load life in humidity
Overload rated voltage or Max.working voltage (get the lower) for 1000 hours (1.5 hours on and half-hour off ) at the 40±2℃ and 90~95% relative humidity.
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±2℃.
