電(dian)(dian)(dian)(dian)子元器(qi)件(jian)(jian)包括：電(dian)(dian)(dian)(dian)阻、電(dian)(dian)(dian)(dian)容器(qi)、電(dian)(dian)(dian)(dian)位器(qi)、電(dian)(dian)(dian)(dian)子管、散熱器(qi)、機(ji)(ji)電(dian)(dian)(dian)(dian)元件(jian)(jian)、連接器(qi)、半導體分立(li)器(qi)件(jian)(jian)、電(dian)(dian)(dian)(dian)聲器(qi)件(jian)(jian)、激光器(qi)件(jian)(jian)、電(dian)(dian)(dian)(dian)子顯示(shi)器(qi)件(jian)(jian)、光電(dian)(dian)(dian)(dian)器(qi)件(jian)(jian)、傳感器(qi)、電(dian)(dian)(dian)(dian)源、開(kai)關(guan)、微(wei)特電(dian)(dian)(dian)(dian)機(ji)(ji)、電(dian)(dian)(dian)(dian)子變(bian)壓器(qi)、繼電(dian)(dian)(dian)(dian)器(qi)、印(yin)制電(dian)(dian)(dian)(dian)路(lu)(lu)板(ban)、集成電(dian)(dian)(dian)(dian)路(lu)(lu)、各類(lei)電(dian)(dian)(dian)(dian)路(lu)(lu)、壓電(dian)(dian)(dian)(dian)、晶體、石英、陶瓷磁性材料(liao)、印(yin)刷電(dian)(dian)(dian)(dian)路(lu)(lu)用基(ji)材基(ji)板(ban)、電(dian)(dian)(dian)(dian)子功能工藝專用材料(liao)、電(dian)(dian)(dian)(dian)子膠（帶）制品、電(dian)(dian)(dian)(dian)子化學材料(liao)及部品等。

電子元件符號認識

電子元件有許多(duo)種，為了區分一般用(yong)(yong)“字母+數字”的形式表(biao)示(shi)(shi)。電阻用(yong)(yong)“R+數字”表(biao)示(shi)(shi)，電容用(yong)(yong)“C+數字”表(biao)示(shi)(shi)，電容容量誤差表(biao)符號為F、G、J、K、L、M，晶(jing)體二極(ji)管(guan)用(yong)(yong)“D+數字”表(biao)示(shi)(shi)，穩壓二極(ji)管(guan)用(yong)(yong)“ZD+數字”表(biao)示(shi)(shi)，電感用(yong)(yong)“L+數字”表(biao)示(shi)(shi)，晶(jing)體三(san)極(ji)管(guan)用(yong)(yong)“Q+數字”表(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(pin)的(de)質(zhi)量。此(ci)外要(yao)考(kao)慮電子元件的(de)型號細節(jie)部分(fen)，如(ru)產品(pin)的(de)誤(wu)差、材(cai)質(zhi)等(deng)。最后需(xu)要(yao)控制成(cheng)本，考(kao)慮性價比方面的(de)需(xu)求，切勿(wu)貪小(xiao)便宜，可以先小(xiao)批量采樣(yang)再(zai)大規模采購(gou)。

電子元件的作用

1、繼電器(qi)：在電路中(zhong)起著自動調節、安(an)全保(bao)護(hu)、轉(zhuan)換電路等作(zuo)用。

2、電容器(qi)：應用于隔直，耦(ou)合(he)，旁路，濾波(bo)，調諧回路， 能量(liang)轉換，控制電路等方面。

3、連接器(qi)：連接兩個有(you)源器(qi)件的器(qi)件，傳輸電流或信號(hao)。

4、電位器(qi)：用(yong)于分壓的可變電阻(zu)器(qi)。
