无论是膜式的电阻还是合金的电阻,通过精密的调阻工艺都可以达到很高的初始精度。
但电阻在使用前要经过运输,存储,焊接等过程,这些过程都会造成电阻阻值的变化。
另外电阻需要在不同的环境温度下工作,同时加载功率也会使电阻产生自热,这些因素都会使阻值发生不可逆的变化。
高精密的电阻必须同时具有高稳定性的特点。
电阻的稳定性比初始精度更重要最快24小时交货,无最小起定量限制开步电子常备箔电阻芯片,可以满足小批量快速交付。
从用户下单到发货最快24小时完成,1且不设最小订购量,即使1片也可以订购。
每只箔电阻出厂前都经过严格的测试程序,确保符合性能指标。
不受阻值标准约束,可任意定义需要的阻值每只箔电阻都要经过调阻,通过切断边缘区域的调阻带从而增加阻值,达到调整阻值的目的。
和其他电阻不同,用户可以任意的定义阻值,不受标准阻值的约束,比如1.234欧。
