????金属膜精密电阻的精度较高，但阻值温度系数和分布参数指标略低；线绕精密电阻的阻值精度和温度系数指标很高，但分布参数指标偏低；金属箔精密电阻的精度、阻值温度系数和分布参数各项指标都很高：精度可达10-6，温度系数可达±0.3×10-6/℃，分布电容可低于0.5pF，分布电感可低于0.1μH。由于上述三类精密电阻器的价格随性能而提高，所以在应用中应根据实际情况合理选用。

????1Ω以下阻值的电阻，一般能达到±1[%]精密度之内，就算做精密电阻范畴了，因为阻值基数很小，就算是1[%]的误差，实际的阻值误差已经很小了。更高精密的可以做到±0.5[%]以内，但工艺要求，技术要求较高。

????电子产品中电阻常按插件电阻，贴片电阻区分。精密电阻当然也会有这个区别。比如贴片式捷比信精密电阻，即是薄膜电阻，相对插件电阻来说，拥有高精度、低温漂（低温度系数）、小体积、适合自动化贴装等性。插件精密电阻按材料分，有金属膜精密电阻、线绕精密电阻和金属箔精密电阻几类。
