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!

盛雷城精密电阻有限公司长期以来，一直在制造世界上稳定性高的电阻器--UPR 系列超高稳定、超、超低温度系数的电阻器，具有小于 20ppm 的连续工作年度变化量！多家用户的长期使用记录提供了可靠的证明！

威世通过收购许多大品牌的的分立电子元件的厂商促进了公司发展，例如：达勒(Dale)、思芬尼（Sfernice）、迪劳瑞(Draloric)、思碧(Sprague)、威趋蒙(Vitramon)、硅尼克斯(Siliconix)、通用半导体(General

Semiconductor)、BC元件（BCcomponents）和贝士拉革(Beyschlag)。

盛雷城精密电阻有限公司生产的高精密电阻器和高精度电阻器已经成功替代了VISHAY(威世) 收购的许多大品牌的电阻生产厂家的电阻器。

Thunder Precision resistors provide a lot of replacement for those made by Vishay's company for a long long time!

普通电阻器包括薄膜电阻器、绕线电阻器、实心电阻器；精密电阻器包括金属膜精密电阻、绕线精密电阻、金属箔精密电阻等。盛雷城精密电阻有近三十年电阻制造经验，生产的金属膜、碳膜、氧化膜等普通电阻应用于格力电器的空调产品、金属膜配套电阻广泛应用于全国的数字万用表厂家、高精密模压电阻为仪表和衡器天平提供了有力的配件支持，而精密可达万分之一，温度系数低至1PPM的超高精密电阻产品受精密分析仪器厂家高度认可。

Ordinary resistors include Thin film resistors,Wirewound resistors,Solid core resistor. Precision resistors include Metal film precision resistors, Wirewound precision resistors, Metal foil precision resistors etc. Thunder precision resistors has manufacture experience nealy 30 years, our metal film,carbon film, oxide film products mainly used in Gree products. Metal film matching resistors are widely used in almost all of the DMM manufactures in China, 

high precision resistors has been the great support to weighting scales manufactures as well as test Meters manufactures all over the world. The ultra high precision resistors with tolerance up to 0.01% and ultra low TCR with lower to 1PPM/℃ are highly admitted by precision analysis instruments manufactures.
