德銘特電阻色碼系統識別 |
|||||||
世界知名元器件制造商 TOKEN (德銘特被動元器件) 固定電阻器的色碼色環標示識別,主要應用於圓柱型的電阻器上,如:碳膜電阻、氧化膜電阻、精密電阻、耐沖擊電阻、保險絲電阻、實芯電阻、實芯電阻、保險絲電阻、繞線電阻、突波電阻。在早期,一般當電阻的表面不足以用數字表示法時,就會用色碼色環標示法來表示電阻的阻值,公差,規格。現在,色碼色環標示法已應用於TOKEN 的自動化生產設備上。TOKEN 生產的電阻器上的色碼色環,非常易於識別,前後端易於區分。TOKEN 的色碼色環,主要分成兩部分:
第一部分的每一條色環都是等距,自成一組,易於區分第二部分的色環。帶有四個色環的其中第一、二環分別代表兩位有效數的阻值;第三環代表倍率;第四環代表誤差,帶有五個色環比四色環多了一個有效數字。 TOKEN 的第五條色環如為黑色,一般用來表示為繞線電阻器,第五條色環如為白色,一般用來表示為保險絲電阻器。如果電阻體只有中間一條黑色的色環,則代表此電阻為零歐姆電阻。 |
