盛雷城精密电阻有限公司生产制造的RJM73U0204和 RJM74U0207系列超晶圆电阻器具有超高稳定性和可靠性，是VISHAY公司 UMA0204 和 UMB0207系列的完全替代产品。

Ultra-precision melf type resistors series RJM73U0204 and RJM74U0207 are of ultra high stability and reliability. They are the right cross to Vishay's UMA0204 and UMB0207.

Melf type wire wound fusible resistors are the new resistors made by Thunder Precision Resistor Co.in 2013.

Melf type wire wound fusible resistorsare used to as safety protection components with small size and high power capability and adjustable fusing power rating and fusible time duration. 

线绕熔断电阻器是近些年来研发出来的新型熔断电阻器，晶圆型熔断电阻器也就是MELF 型线绕熔断电阻器是盛雷城精密电阻有限公司近年来退出的新型产品，产品具有体积小，功率密度高，熔断功率和熔断时间可以根据用户的实际实际需要进行调整，所以具有无可替代的优越性。TheannualeralrankauditedbyBYDareallAgrade,thehighestgradeforalltheyearstillnow。

盛雷城精密电阻有限公司很早就开始采用欧洲和美国先进的生产工艺和材料，为精密仪器仪表和精密衡器以及电子天平等生产企业提供具有较高要求的EE系列模压型电阻器，这种电阻采用黑色的硅胶塑封成型，俗称为黑电阻，具有很高的稳定性和可靠性以及非常小的温度系数， 其高稳定性、高可靠性、超、低TCR的特性， 得到了高品质仪器仪表客户的和肯定。TUV等认证，专业开发和生产各类精密电阻并根据客户不同的参数要求，不同的领域，不同的安装方式来定制符合要求的各类高精密电阻。

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 re 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, Because of its high stability, high reliability, high precision, low TCR properties, the products are obtained high instrumentation customers' praise and recognition.
