盛雷城精密電阻（江西）有限公司主營(yíng)：精密電阻,高壓電阻,晶圓電阻,電阻網(wǎng)絡(luò),高精密電阻等

高精密電阻,是指電阻的阻值誤差小于0.10%、電阻的熱穩(wěn)定性(溫度系數(shù))低于25ppm/℃ 達(dá)到一定標(biāo)準(zhǔn)的電阻器.  高精密電阻按材料分,有金屬膜精密電阻、線繞精密電阻和金屬箔精密電阻幾類.
 Ultra precision resistors are those with tighten tolerance such as tolerance less than 0.10%. Thunder Precision Resistors are the one of the experts of ultra precision resistors in the world.

Ultra precision resistors are made of high grade ceramic cores from Germany and the alloy film from United State. 

resistors are ideal for use in direct current (D.C.) electrical circuits & compliant with international directives, we specialize in wire wound resistors, sensors, shunts & RTD compensators featuring highly stable artificially aged components featuring close precision tolerances from ±1% to ±0.005% and low temperature coefficients (T.C.) to 0±1 PPM/°C.

電阻元件的電阻值大小一般與溫度，材料，長(zhǎng)度，還有橫截面積有關(guān)，衡量電阻受溫度影響大小的物理量是溫度系數(shù)，其定義為溫度每升高1℃時(shí)電阻值發(fā)生變化的百分?jǐn)?shù)。電阻的主要物理特征是變電能為熱能，也可說(shuō)它是一個(gè)耗能元件，電流經(jīng)過(guò)它就產(chǎn)生內(nèi)能。電阻在電路中通常起分壓、分流的作用。對(duì)信號(hào)來(lái)說(shuō)，交流與直流信號(hào)都可以通過(guò)電阻。

Precision resistors is of low tolerance and low temperature coefficient, Thunder Precision Resistors makes ultra precision resistors and ultra precision resistor networks.
