電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)元(yuan)(yuan)器(qi)(qi)件(jian)包括：電(dian)(dian)(dian)(dian)(dian)(dian)阻、電(dian)(dian)(dian)(dian)(dian)(dian)容器(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)位器(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)管、散熱器(qi)(qi)、機電(dian)(dian)(dian)(dian)(dian)(dian)元(yuan)(yuan)件(jian)、連接(jie)器(qi)(qi)、半(ban)導體(ti)分立器(qi)(qi)件(jian)、電(dian)(dian)(dian)(dian)(dian)(dian)聲器(qi)(qi)件(jian)、激光器(qi)(qi)件(jian)、電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)顯示器(qi)(qi)件(jian)、光電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)件(jian)、傳(chuan)感(gan)器(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)源、開關(guan)、微特電(dian)(dian)(dian)(dian)(dian)(dian)機、電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)變壓器(qi)(qi)、繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)、印(yin)制電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)板、集成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)、各類(lei)電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)、壓電(dian)(dian)(dian)(dian)(dian)(dian)、晶體(ti)、石(shi)英、陶(tao)瓷磁(ci)性材料(liao)、印(yin)刷電(dian)(dian)(dian)(dian)(dian)(dian)路(lu)用(yong)基(ji)材基(ji)板、電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)功(gong)能工藝專用(yong)材料(liao)、電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)膠（帶）制品(pin)、電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)化(hua)學材料(liao)及部品(pin)等。

電子元件符號認識

電(dian)子元件(jian)有許多(duo)種，為了區分(fen)一般(ban)用“字(zi)母+數字(zi)”的形式表示(shi)。電(dian)阻用“R+數字(zi)”表示(shi)，電(dian)容用“C+數字(zi)”表示(shi)，電(dian)容容量(liang)誤差(cha)表符號為F、G、J、K、L、M，晶體(ti)二(er)極(ji)管用“D+數字(zi)”表示(shi)，穩壓(ya)二(er)極(ji)管用“ZD+數字(zi)”表示(shi)，電(dian)感用“L+數字(zi)”表示(shi)，晶體(ti)三極(ji)管用“Q+數字(zi)”表示(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保障產品的質量。此外要考慮電子元件的型(xing)號細節(jie)部分，如產品的誤(wu)差、材質等。最后需要控(kong)制成本，考慮性價比方面的需求，切勿(wu)貪小便宜，可以先小批量采(cai)樣再大規模(mo)采(cai)購。

電子元件的作用

1、繼電器：在電路中起著自動(dong)調節、安全保護、轉(zhuan)換電路等(deng)作用。

2、電(dian)容(rong)器：應(ying)用于(yu)隔直，耦合，旁路，濾波，調諧回路， 能量轉(zhuan)換，控制電(dian)路等方面。

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

4、電(dian)位器：用于(yu)分壓的(de)可(ke)變電(dian)阻(zu)器。
