貼片電阻是怎么分類(lèi)的？
貼片電阻怎么識(shí)別？比如說(shuō)0805怎么跟1206去區(qū)分？

電阻不管 0603, 0805 , 1206其實(shí)大多用英制去算, 若用公制那就好算多了.....
1000mil = 25.4mm , 所以 1mm = 39.37mil
0603為長(zhǎng) 60mil, 寬 30mil 所以長(zhǎng) 60mil / 39.37 = 1.52mm 寬30mil / 39.37 = 0.76mm
0805為長(zhǎng) 80mil, 寬 50mil 所以長(zhǎng) 80mil / 39.37 = 2.03mm 寬50mil / 39.37 = 1.27mm
1206為長(zhǎng) 120mil 寬 60mil 所以長(zhǎng) 120mil/ 39.37 = 3.04mm 寬60mil /39.37 = 1.52mm
以此類(lèi)推.......................................

0603 0805 1206已經(jīng)是英寸了
所以換算為mm應(yīng)當(dāng)分別是 1608 2012 3216
直接乘2.54
