高精密電阻器是什么？

很多工程技術(shù)人員都認(rèn)為，精度高的電阻就是高精密電阻器，百度百科也錯誤地收錄了這樣的信息，以至于以訛傳訛，誤導(dǎo)了大家。

What is high precision resistors? Almost all techniciens think the resistors with tight tolerance are high precision resistors. It is not correct since the real meaning of high precision resistors are the resistors with high stability since without stability the tolerance is meaningless!

High precision resistors are made by professional manufacturers instead of sorting by most manufacturers or dealers from normal resistors since there is no real requeset of stability for normal reistors!

高精密電阻器真正的定義應(yīng)該是具有高穩(wěn)定性的電阻器，高精密電阻器的電阻阻值精度可以是0.01%，0.05%， 甚至可以是1%，但是，高精密電阻器的穩(wěn)定性指標(biāo)不論其實際精度都是一樣的，不論是0.01%，0.05%， 甚至是1%，其年度漂移指標(biāo)都要小于50ppm！

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.  

盛雷城精密電阻于1988年以40萬美元的價格從歐美引進了高可靠性和高穩(wěn)定性的金屬膜電阻器的先進生產(chǎn)工藝，至今已具有近三十年生產(chǎn)制造精密電阻的經(jīng)驗，根據(jù)實際生產(chǎn)過程與試驗過程的經(jīng)驗總結(jié)分析，進行了進一步的改進與完善，為廣大客戶提供多樣化的電阻解決方案。
