電子元件符號認識

電子元件有許多種(zhong)，為(wei)了(le)區(qu)分一般用(yong)“字(zi)(zi)母(mu)+數字(zi)(zi)”的形(xing)式表(biao)(biao)(biao)示(shi)(shi)。電阻用(yong)“R+數字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，電容用(yong)“C+數字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，電容容量誤差表(biao)(biao)(biao)符號為(wei)F、G、J、K、L、M，晶體二極(ji)管用(yong)“D+數字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，穩(wen)壓(ya)二極(ji)管用(yong)“ZD+數字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，電感用(yong)“L+數字(zi)(zi)”表(biao)(biao)(biao)示(shi)(shi)，晶體三極(ji)管用(yong)“Q+數字(zi)(zi)”表(biao)(biao)(biao)示(shi)(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保障產品的質量(liang)。此外要(yao)考慮(lv)電子元件的型號細節(jie)部分，如產品的誤差、材質等。最(zui)后需要(yao)控制(zhi)成(cheng)本，考慮(lv)性價比(bi)方面的需求，切勿(wu)貪小便宜(yi)，可以先小批(pi)量(liang)采樣(yang)再大規(gui)模采購。

電子元件的作用

1、繼(ji)電器：在電路中起(qi)著自動調節、安全保護、轉換電路等作用。

2、電(dian)容器：應用于隔直(zhi)，耦合(he)，旁路，濾波(bo)，調諧回(hui)路， 能(neng)量轉換，控制(zhi)電(dian)路等方面。

3、連(lian)接器(qi)：連(lian)接兩個有源器(qi)件(jian)(jian)的器(qi)件(jian)(jian)，傳輸電流(liu)或信號。

4、電位器：用(yong)于分壓的(de)可變電阻(zu)器。
