高精密電阻器, 簡稱高精密電阻，是精密電子電路設(shè)計時常會用到。高精密電阻主要是作為采樣電阻使用.
金屬箔精密電阻的精度、阻值溫度系數(shù)和分布參數(shù)各項指標都很高:精度可達0.005%,溫度系數(shù)可達±0.5×10-6/℃,分布電容可低于0.5pF,分布電感可低于0.1μH.
UPR型超高精密金屬膜電阻器 -- 盛雷城精密電阻有限公司生產(chǎn)制造的，可以替代金屬箔電阻。

the UPR series ultra-precision resistors made by Thunder Precision Resistors are the perfect replacement of metal foil resistors that had been proved by a lot of our customers.

盛雷城精密電阻推出的精密分流電阻器、電流傳感器具有在直流應(yīng)用環(huán)境中非常重要的低熱電勢（EMF）優(yōu)異性能，新的焊接技術(shù)減少了兩種材料結(jié)合部位的溫差，從而大幅度降低了熱電勢效應(yīng)的影響，并使得焊接材料與電子材料的熱特性進一步相近與兼容，降低了熱點相應(yīng)。

Thunder Precision Resistor Co., Ltd. Provide high precision current sensors with quite low EMF that take very important part in

the DC current utility and application by new soldering technology to reduce the temperature gradient. Compatible soldering materials and the resistance materials adopted is quite useful to reduce the hot spot effects in the application.  

The resistor is a passive electrical component to create resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms. An ohm is the resistance that occurs when a current of one ampere passes through a resistor with a one volt drop across its terminals. The current is proportional to the voltage across the terminal ends. This ratio is  represented by Ohm’s law:
