電子元件符號認識

電子元件有許(xu)多種，為(wei)(wei)了區(qu)分一般(ban)用“字(zi)母(mu)+數(shu)字(zi)”的形式表(biao)(biao)示(shi)。電阻(zu)用“R+數(shu)字(zi)”表(biao)(biao)示(shi)，電容用“C+數(shu)字(zi)”表(biao)(biao)示(shi)，電容容量(liang)誤差表(biao)(biao)符號為(wei)(wei)F、G、J、K、L、M，晶(jing)體(ti)二極管(guan)(guan)用“D+數(shu)字(zi)”表(biao)(biao)示(shi)，穩壓二極管(guan)(guan)用“ZD+數(shu)字(zi)”表(biao)(biao)示(shi)，電感用“L+數(shu)字(zi)”表(biao)(biao)示(shi)，晶(jing)體(ti)三極管(guan)(guan)用“Q+數(shu)字(zi)”表(biao)(biao)示(shi)。

電子元件采購注意事項

最需要注意的是找正規工商注冊的公司進行采購，了解供應商資質，三證是否齊全，只有優質的電子元件品牌才能(neng)保障產品的質(zhi)量(liang)。此(ci)外要(yao)考慮電子元(yuan)件的型號細節部分(fen)，如產品的誤差、材(cai)質(zhi)等。最后(hou)需要(yao)控制(zhi)成本，考慮性價比方(fang)面(mian)的需求，切(qie)勿(wu)貪小便宜，可以先小批量(liang)采(cai)樣再(zai)大規(gui)模采(cai)購。

電子元件的作用

1、繼(ji)電器：在電路中起著(zhu)自動調節(jie)、安全保護、轉換電路等作(zuo)用。

2、電容器：應用于隔(ge)直，耦合，旁路(lu)，濾波(bo)，調諧回路(lu)， 能量轉(zhuan)換，控(kong)制電路(lu)等方(fang)面。

3、連接器(qi)：連接兩個(ge)有源器(qi)件的器(qi)件，傳輸電流(liu)或信號。

4、電(dian)位(wei)器：用于分壓的可變電(dian)阻(zu)器。
