電子元件符號認識

電(dian)子(zi)元件(jian)有許多種，為了區分(fen)一般用“字(zi)母+數字(zi)”的形式表(biao)(biao)(biao)示(shi)(shi)。電(dian)阻用“R+數字(zi)”表(biao)(biao)(biao)示(shi)(shi)，電(dian)容(rong)用“C+數字(zi)”表(biao)(biao)(biao)示(shi)(shi)，電(dian)容(rong)容(rong)量誤(wu)差表(biao)(biao)(biao)符號為F、G、J、K、L、M，晶體二極管(guan)用“D+數字(zi)”表(biao)(biao)(biao)示(shi)(shi)，穩壓二極管(guan)用“ZD+數字(zi)”表(biao)(biao)(biao)示(shi)(shi)，電(dian)感用“L+數字(zi)”表(biao)(biao)(biao)示(shi)(shi)，晶體三極管(guan)用“Q+數字(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(bao)障產品的質(zhi)量(liang)。此外(wai)要考慮(lv)電子元件(jian)的型號(hao)細節(jie)部分，如產品的誤差、材(cai)質(zhi)等。最后需要控制成本，考慮(lv)性價比方面(mian)的需求，切勿(wu)貪小(xiao)(xiao)便宜，可以先小(xiao)(xiao)批量(liang)采(cai)樣再大規模采(cai)購。

電子元件的作用

1、繼電(dian)器：在電(dian)路(lu)中起著自動調節、安全保護、轉換電(dian)路(lu)等作用。

2、電容器(qi)：應用(yong)于隔直，耦合(he)，旁路(lu)，濾(lv)波，調諧回路(lu)， 能量轉換(huan)，控制(zhi)電路(lu)等方(fang)面。

3、連接器：連接兩個有源器件(jian)的器件(jian)，傳輸電流或信號。

4、電位(wei)器(qi)：用于分壓(ya)的(de)可變電阻器(qi)。
