upr精密電阻 盛雷城 upr精密電阻研發(fā)

盛雷城精密電阻發(fā)明的upr系列模壓型精密電阻器，通過模壓，硅膠塑封使其性能趨于相當(dāng)?shù)姆�(wěn)定，不易受到外界高低溫、高濕等-環(huán)境的影響，性能表現(xiàn)優(yōu)異，可用于取代部分的vashy aur系列和fpr、fps 系列金屬箔電阻器

- precision resistor co., ltd. had a patent on molding type upr series for more than 20 years. the molding type is much  better protected from dampt&bad circumstances.

在電子電路中，電阻起著阻礙電流的作用，電路中多了電阻器后電路中的電流會(huì)減小，普通電阻器是也是在電子電路中使用量的電阻器，精密電阻器的阻值更為精密，廣泛應(yīng)用于數(shù)字萬用表、高精密的儀器儀表、衡器天平等產(chǎn)品中，盛雷城精密電阻有限公司生產(chǎn)的高精密電阻，具有精度高，溫度系數(shù)低，受環(huán)境溫度的影響更小等特性。精密可-萬分之一，溫度系數(shù)低至1ppm。

in the electronic circuit, the resistance play a negative role of current¤t in the circuit resistor in the circuit after much will decrease, is the most commonly used ordinary resistor resistor is used in most electronic circuits, precision resistor values are more sophisticated&widely used in digital form by the million, high precision instrument. weighing scales&other products, the high precision resistor which manufactured by- precision resistor co.,ltd. with high precision, low temperature coefficient, less affected by the environmental temperature&other characteristics. the tol. can reach 0.01%, tcr can be lower to 1ppm.
