    盛雷城精密電阻使用德國CERAMTAC生產的含鋁量96%的高鋁瓷棒，和美國的鍍膜靶材，嚴格按照從歐洲引進的生產工藝，使用激光調阻和高溫模壓等一系列特殊工序生產制造的 RN 系列軍標電阻，符合與滿足美國軍標 MIL-R-55182 和中國軍標GJB1929-94，長期穩定性非常高，電壓噪聲和電流噪聲都非常小，適用于航天航空精密儀器儀表的采樣道路，基準電路。

RN SERIES MILITARY STANDARD METAL FILM RESISTORS IS ONE OF THE MAIN PRODUCTS OF THUNDER PRECISION RESISTORS, INTRODUCED FROM EUROPE IN 1989, IT IS THE ONE MOST POPULAR SERIES WITH ESTABLISHED RELIABILITY.

線繞電阻的線材直接決定了電阻的溫飄和阻值的大小，也影響電阻的短時過載能力和阻值的長期穩定性。

鎳鉻合金是最常用的線材，但各個線材供應廠家的質量和工藝千差萬別，合金中微量元素的成份也不盡相同。

高質量的線材在高溫燒結的過程中電性能變化很少，質量穩定。

同樣大小的基體繞制不同等級的線材所得到的阻值范圍差別很大。這就是為什么同等功率的線繞電阻，國內廠家往往只能做到千歐級別，國外廠家可以做到上百千歐甚至幾十兆歐姆。不同的阻值，不同的功率，需要選擇不同的線號。

盛雷城精密電阻有限公司使用優質的進口特種合金絲上次高精密線繞電阻，阻值范圍大，溫度系數低，穩定性高。

Thunder Precision Resistor Co., Ltd. make precision wire wound resistors with the high quality alloy wire imported to keep the high stablility of the precision wire wound resistors as well as high resistance range.

All resistors come with a tolerance value, which is given as a percentage. The tolerance value tells us how close to the nominal value a resistance can vary. For example, a 500? resistor that has a tolerance value of 10%, may have a resistance that is somewhere between 10% above 500? (550?) or 10% below 500? (450?). If the same resistor has a tolerance of 1%, its resistance will only vary by 1%. Therefore, a 500? resistor can then vary between 495? and 505?.
