怎样识别色码电感,怎样识别色环电感
色环电感的标注方法基本与色环电阻是一致的,只是从外观上面看上去,色环电感比色环电阻看上去会更加粗一些。 具体请对照下面的表格和表格下面的三个例子。

*例如e.g. :
标称电感量及偏差为22uH,±5%的电感器其色码为:红+红+黑+金;
If nominal inductance & tolerance is22uH,±5%, respectively red+red+black+gold should be marked;
标称电感量及偏差为1.0uH,±10%的电感器其色码为:棕+黑+金+银;
If nominal inductance & tolerance is 1.0uH,±10%, respectively brown+black+gold+silver should be marked;
标称电感量及偏差为0.22uH,±20%的电感器其色码为:红+红+银+黑。
If nominal inductance & tolerance is 0.22uH,±20%, respectively red+red+silver+black should be marked.
备注:LGA0204 由于体长较小,只标注前三条代表标称电感量的色码。
NOTE: Only the first three color zones are marked on the body of LGA0204,due to the small body size.
