Thunder Precision Resistor Co.， Ltd. makes the highest stability resistors in the world for many years.

UPR series ultra precision resistors are the right cross to Vishay's AUR series and FPR， FPS series metal foil resistors and had been adopted by many customers for many years.

UPR series ultra precision resistors are of the highest stability of the resistors with less than 20ppm annual drift in cectively working year!

盛雷城精密電阻有限公司長期以來，一直在制造世界上穩定性高的電阻器--UPR 系列超高穩定、超、超低溫度系數的電阻器，具有小于 20ppm 的連續工作年度變化量！多家用戶的長期使用記錄提供了可靠的證明！

盛雷城精密電阻有限公司很早就開始采用歐洲和美國的生產工藝和材料，為精密儀器儀表和精密衡器以及電子天平等生產企業提供具有較高要求的EE系列模壓型電阻器，這種電阻采用黑色的硅膠塑封成型，俗稱為黑電阻，具有很高的穩定性和可靠性以及非常小的溫度系數，惠州精密電阻，?其高穩定性、高可靠性、超、低TCR的特性， 得到了儀器儀表客戶的一致好評和肯定。

THUNDER Precision Resistor Co. Ltd. started every ?earlier to use the advanced production technology and material from?Europe and the United States.The company provide EE series molded type resistor to fulfill high requirement for precision instruments， precision electronic balance， weighing apparatus and other production enterprises. This kind of ?resistances mold with silicone， commonly known as black resistance. it has very high stability and reliability as well as the temperature coefficient is very?lower，UAR精密電阻0.1%， Because of its high stability， high reliability， high precision，模壓精密電阻0.1%， low TCR properties， the products are obtained high quality instrumentation customers' praise and recognition.
