理論電阻值沒有偏差，但實際上，由于制造工藝和使用環境的影響，電阻值會有一定程度的波動。例如，100歐姆的電阻可能變成105歐姆，因此電阻值與理想電阻值之間存在一定的誤差，誤差非常小。電阻值非常穩定的電阻是<a

src="/u_file/2103/photo/2103/2021031616330734.jpeg" /></div> <span style="line-height:200%;"><span style="font-size:15px;"><span style="font-family:微軟雅黑,arial;"> 任何產品以及普通電阻器都有精度要求。然而，偏差為±5％的一般電阻電容精度不會影響使用。然而，在某些情況下，例如用于通過部分電壓測量電壓的電阻或串聯到電路以測量電流的電阻，要求相對較高。此時，需要使用所謂的精密電阻器，<br /> 例如，在這個圖中，需要串聯兩個電阻器來獲取電壓，然后給單片機的ad端口提供一定的值。如果電阻偏差相對較大，則無法準確測量鋰電池兩端的電壓。這將導致電壓測量的偏差，影響鋰電池電壓的判斷，并可能因過度充電或放電而燒毀鋰電池。<br /> 電阻具有溫度漂移的特性，即溫度的變化會使電阻發生變化。如果使用普通電阻，在測量過程中高溫和低溫也會影響精度，因此有必要使用精密電阻。<br /> 電阻如果長期使用會老化，也會導致一些功能不合格。<br /> 更常見的精密電阻器有塊電阻器、繞組電阻器和金屬膜電阻器。</span></span></span> <hr />方案推薦：<a href="http://www.forsakring-online.com/products/category-75/"><strong><span
