/> 精密電阻器<br /> 在車身結構的制造過程中合金電阻分為鎳銅合金和錳銅合金性能指標，五個關鍵性能指標：P（功率）和V（電壓）和I（電流）和R（電阻）和TCR（溫度漂移）電流采樣電阻計算公式：I=√ p/r1的合金電阻。功率：通過電流時焦耳熱阻產生的功率的是貼片電阻的功率。根據焦耳定律：p=i2r2，額定功率：通常指環境溫度為70°C時的額定功率和溫度下的最大允許功率。額定電壓：額定電壓v=√ P可按下式×R4計算。最大工作電壓：貼片電阻器5兩端允許加載的最大電壓。額定電流：i=√ p/rt.c.r（電阻溫度系數）與電阻值之間的關系。T.C.R.使用的單位中的Ppm％是1％，而Ppm是溫度漂移的百萬分之一。在計算電阻時，每1℃的溫度變化都會導致電阻值的變化。其計算為50℃工作溫度下的原始電阻正負（電阻×**Ppm），電阻范圍為20.075mΩ-19.925mΩ。溫度漂移正負點的應用：+溫度漂移表示電阻值隨溫度升高而增大，隨溫度降低而減小-溫度漂移表示電阻值隨溫度升高而減小，隨溫度降低而增大。T、 C.R和阻力百分比比率之間的關系。冠發電阻器提供電阻器、精密電阻器、片式電阻器、插入式電阻器、圓柱形電阻器、圓柱形電阻器、圓柱形電阻器、無針電阻器、高精度電阻器、插入式電阻器封裝、插入式電阻器等。</span></span></span> <hr /><span style="line-height:200%;"><span style="font-size:15px;"><span
