PRECISION RESISTORS AND PRECISION RESISTOR NETWORKS ARE THE MAIN PRODUCTS OF THUNDER PRECISION RESISTORS

 

瓷棒的  AL2O3含鋁量 決定電阻器的導熱性能、絕緣性能、均勻性，硬度和表面光潔度等，AL2O3含鋁量越高，各項指標就越好。德國赫斯特生產的708瓷棒，AL2O3含鋁量為96％。

AL2O3 content of the ceramic rods of the precision resistors influence the heat transmission, insulation, hardness, fineness of the surface of the rods, all the these willl influence the stability of the precision resisgtors.

708 is the type of the ceramic rods made by CERAMICTEC of Germany with AL2O3 content more than 96% and it is the main ceramic rods adopted by Thunder Precision Resistors more than 25 years!

     

Actually, I am trying to build a current monitor for a wireless sensor network. I am going to use a current sense resistor as the current will pass through the resistor. By measuring the value of the voltage, the current value can be calculated.

My application is very sensitive as the current that will be measured is in the range of mA, 30 mA maximum.

When it came to buying the resistors I got confused. I found a type of resistor called 'precision resistor' that has a very small error, and another one called 'current sense resistor'. I wasn’t sure what were the differences between these to types of resistors, not until one day I reached out to Thunder-precision resistor, their customer service department presented a clear explanation to me.
